Suno v4 Review: Is AI Music Finally Good Enough to Release?

By Ted · March 4, 2026

When Suno first hit the scene, it was a novelty — fun to play with, but nobody was putting those tracks on Spotify. With v4, that conversation has fundamentally changed. I’ve spent the last three weeks putting Suno v4 through its paces, generating everything from lo-fi beats to full orchestral arrangements, and the results are genuinely surprising.

What’s New in Suno v4

The headline feature is extended generation — you can now create tracks up to 4 minutes long in a single generation, up from the 2-minute limit of v3.5. But the real upgrade is under the hood. The audio quality has taken a massive leap forward. Gone are the muddy mids and that telltale “AI warble” that plagued earlier versions.

The new style control system lets you dial in genres with much more precision. Instead of just typing “jazz” and hoping for the best, you can specify sub-genres, era influences, and even reference specific production styles. Want “90s boom-bap with vinyl crackle and a jazzy Rhodes loop”? Suno v4 actually understands what that means now.

Audio Quality: The Big Jump

Let’s talk about what everyone cares about — does it sound good? The short answer: yes, with caveats. Instrumental tracks are where Suno v4 truly shines. Electronic, ambient, lo-fi, and cinematic genres sound nearly indistinguishable from human-produced music. The AI has clearly been trained on higher-quality source material, and it shows.

Vocals are still the weak point, but they’ve improved dramatically. Male vocals in rock and hip-hop styles sound natural about 70% of the time. Female pop vocals are hit-or-miss — sometimes stunning, sometimes falling into uncanny valley territory. The trick is regenerating until you get a good take, which the new batch generation feature makes much easier.

Lyrics and Song Structure

Suno’s lyric generation has always been decent, but v4 introduces custom lyrics mode that actually respects your syllable counts and rhyme schemes. You can paste in your own lyrics and the AI will fit them to the melody naturally, rather than awkwardly cramming words into measures like it used to.

Song structure is more coherent too. Tracks now reliably follow verse-chorus-verse patterns, with proper bridges and outros. The AI seems to understand musical tension and release in a way that previous versions simply didn’t.

The Verdict

Suno v4 is the first AI music tool I’d genuinely recommend for content creators, producers looking for inspiration, and musicians who want to prototype ideas quickly. It’s not replacing session musicians or professional producers — but it’s filling a gap that nothing else could. For $10/month on the Pro plan, it’s absurdly good value.

Rating: 8.5/10 — A genuine leap forward. The best AI music generator available right now for full song creation.

Best for: Content creators, producers seeking inspiration, rapid prototyping
Not ideal for: Professional vocal tracks, live instrument replacement
Price: Free tier available, Pro at $10/month, Premier at $30/month
