Of course you can use a cover version as your original to start with. The results are in most cases very interesting.

I tried this for the first time on a song I co-wrote and recorded in 2008. The quality of my original wasn't too good. Back then I wasn't too sure of what I was doing in the studio.
This is my original recording I did back in 2008: https://soundclick.com/share.cfm?id=7187411
Here is the cover version that Suno generated: https://soundclick.com/share.cfm?id=14926149

I have cover versions that are even closer to my original but I liked the intro of this one much better than my original. As you can hear, Suno uses my lyrics, my chords, my melodies and even my vocal variations that I sang. It generated the whole song even though I only uploaded the first two minutes. This has nothing to do with tags or lyric structure. Suno creates a cover of the audio material that you upload.

This is not a critique... but some songs are more basic than others.
In this particular case, you only had to upload the first 55 seconds for SUNO to have a complete reference. What SUNO produced is actually more dynamic IMO.
