The Future of AI Music Generation

Introduction

In the rapidly evolving world of artificial intelligence, Suno has emerged as a groundbreaking tool for music creation. Launched in December 2023, Suno allows users to generate realistic songs with vocals and instrumentation—or purely instrumental tracks—simply by providing text prompts. As of May 2025, Suno has released its latest version, 4.5, which introduces significant enhancements, making it an even more powerful tool for musicians, content creators, and hobbyists alike. In this blog post, we’ll explore the capabilities of Suno 4.5, delve into its strengths and limitations, and discuss how composers can leverage this technology while preserving their unique creative identity.

Music Composition: Strengths and Limitations

Suno excels in generating music across a wide range of genres, particularly in popular and contemporary styles. Users have reported impressive results in genres such as:

These genres often result in high-quality demos or background tracks suitable for various applications, from social media content to personal projects. For example, a user on X praised Suno for generating ambient music for a drone video, highlighting its utility in content creation X Post by @MelihKarakelle.

However, Suno’s performance is not uniform across all genres. It struggles with more niche or "deep" styles, such as:

In these areas, the generated music may lack the depth, authenticity, or emotional resonance that human composers can provide. Reviews, such as one from Marginal Revolution, note that Suno is best at standardized genres like EDM and heavy metal but struggles with simple, memorable melodies Marginal Revolution.

Additionally, while the instrumental sound quality is initially impressive, repeated listening may reveal a lack of surprise or innovation, as the AI tends to rely on familiar patterns. This observation aligns with user feedback that the music, while technically proficient, may not always offer the "ineffable something" that human-composed music provides.

For lyrics, Suno offers a feature called ReMi, which can generate lyrics based on user prompts. While this is a useful starting point, the generated lyrics often require refinement to achieve the desired quality. Users are encouraged to use other AI tools, such as Gemini, or their own creativity to adjust and improve the lyrics for better coherence and artistic expression. A user on X described a workflow where they generate instrumental tracks with Suno, analyze the mood with Gemini, and then refine lyrics for a self-cover, showcasing a practical approach to lyric refinement X Post by @old_pgmrs_will.

Vocal Quality and Language Support

One of Suno’s standout features is its ability to generate realistic vocals. While the control over vocals is limited compared to professional recording setups, the quality is sufficient for creating demos or conceptual pieces. Reviews note that Suno’s vocals are more credible than earlier AI music generators, with improvements in reducing glitches and robotic tones Suno AI Review.

Suno supports a variety of languages, with varying levels of performance:

This language support allows users to create music in diverse cultural contexts, though performance can vary. For example, Suno can generate high-quality Chinese songs or Russian folk music, but it may encounter difficulties with certain dialects or less standardized languages like Cantonese FLTMAG. For Cantonese, text-based lyrics often fall short, but audio learn covers can still be acceptable for demo purposes.

File Format Details

Suno generates music as WAV files with the following specifications:

This format provides a good balance between audio quality and file size, with enough headroom for further mastering if needed. Additionally, Suno offers stem export capabilities, allowing users to separate the generated music into individual tracks (e.g., drums, piano, vocals) for further editing in digital audio workstations (DAWs) like Logic Pro. However, the separation may not always be perfect, especially for complex arrangements where instruments like piano and synth overlap, limiting the ability to isolate each instrument clearly Suno Wiki.

Advice for Composers: Embracing AI While Preserving Human Touch

As AI music generators like Suno become more advanced, composers face the challenge of distinguishing their work in an increasingly automated landscape. The key to avoiding obsolescence lies in emphasizing the human elements of music creation. Here are some strategies to integrate AI effectively while maintaining originality:

1. Compose from Scratch: While AI can generate impressive demos, starting from scratch with your own ideas ensures originality and a personal touch.
2. Real Recording: Incorporating real instrument recordings and live performances adds authenticity that AI cannot replicate. Avoid relying solely on MIDI to keep the music organic.
3. Improvisation and Personalization: Add improvisational elements, such as humming, local dialects, or unique phrasing, to make your music stand out. For example, incorporating regional dialects can add a cultural depth that AI struggles to achieve.
4. Utilize AI as a Tool: Use AI to speed up the initial stages of composition, such as generating demos or exploring new ideas. Suno can establish a basic prototype, saving time on brainstorming the initial direction. From there, composers can develop the track using their own instruments and paid samples.
5. Refine AI-Generated Lyrics: Use Suno’s ReMi feature to generate initial lyric ideas, but refine them with other AI tools or personal input to ensure they align with the song’s theme and emotional intent.

By combining AI’s efficiency with human creativity, composers can create music that is both innovative and deeply personal. This approach is echoed by users who leverage Suno for quick ideation and then layer their own improvisations to create unique tracks Suno AI Review.

The Controversy Surrounding Suno

Suno has not been without controversy. In June 2024, the Recording Industry Association of America filed a lawsuit against Suno, alleging widespread infringement of copyrighted sound recordings. Additionally, in January 2025, Suno faced another lawsuit from GEMA, the German collection society, for similar copyright concerns. Thousands of musicians have also signed a letter demanding that Suno cease using copyrighted music in its training data, highlighting ethical concerns about AI music generation Wikipedia. Despite these challenges, Suno claims to have safeguards against plagiarism and copyright issues, though it does not disclose its training dataset.

This controversy underscores a broader debate in the music industry: while AI tools like Suno democratize music creation, they raise questions about the value of human artistry and the potential dilution of revenue streams for traditional musicians. Composers using Suno should be aware of these issues and ensure their work complies with copyright regulations, especially when using paid plans that grant ownership of generated music.

Conclusion

Suno 4.5 represents a significant step forward in AI music generation, offering users unprecedented tools to bring their musical ideas to life. Its strengthsව

strengths in popular genres, vocal generation, and creative tools make it a valuable asset for musicians and creators. However, it is not without limitations, particularly in niche genres, language support, and the depth of instrumental sound quality. As AI continues to evolve, the challenge for human composers will be to harness these technologies while preserving the unique, human qualities that make music truly special.

By combining AI’s efficiency with human creativity, composers can create music that is both innovative and deeply personal, ensuring their work remains irreplaceable in the age of AI.
