Hello rvpiano! If a recording of a good performance or a well liked song is flawed, I'll keep it for the value of the music. But even the finest recording of an unwanted song isn't worth keeping, even in these days of streaming which I am just getting used to. Why bother win something you don't want to hear?
If you have a piece of equipment that is the only thing you have that will play certsin media, it may be worth keeping, even if it's performance is second rate.
