How do you ensure the entire song has a consistent sound? My generations always sound a bit different by mid-song.

Whenever I generate a song in Suno, even in the latest 4.5+ model, the second chorus onwards tends to sound noticeably different in terms of the instruments. It's not necessarily embellishment, nor is it really an issue of degrading sound quality. It's just a different version of the same sound of the first chorus.

It's the timbre of all the intstruments that sound different, even if the general melody is the same. Like the percussion, especially the snares sound different. Even the soundstage may sound wider. The fills from synths and guitars sound different, etc. Even with songs under 4 minutes.

Is this unavoidable without resorting to a DAW to clean it up?
