I can't imagine Icarus as "belonging" to anyone but Anne Lister. The way she sings it defines it for me.

There are two things here - a great song may be written by someone who is not a great performer. It can then be sung by somone who is better able to put it across, and become identified as "belonging" to them. Or it may be written by someone whio puts it over well, but it then gets taken up and identified qwith someone more famous. And in that case I wouldn't see it is "belonging" to then latter.

Vin Garbutt does a great job with a song called "Man of the Earth. Bernie Cairns, who did write it, also does a great job when he sings it - but he's not as well known. So many people assume Vin Garbutt write it.

I don't like the idea that songs "belong" to any performer. "Fairytale of New York" sounded like noone else could sing it but Shane McGowan (with Kirsty MacColl) - then Christy Brown sang it, and you saw a whole different set of meanings. (And the great thing with Christy Brown is that he seems able to make songs his in a way that does not stop other people making them theirs, and now it seems everyone feels free to sing Fairtytale.)
