Lyrics are fun/interesting that way - poetry, prose playwrighting can all exist independently
Lyrics admit that they are just part of a larger whole
So you can have a situation where Indigo Girls cover Dire Straits’s Roman and Juliet and they end up being very different songs even though they’re the same lyrically
I mean any Tori Amos cover is a very different song than the original
So what really are lyrics??
