You know the Pearl Jam song, Better Man ("She lies and says she's in love with him. Can't find a better man" etc). Had that song been previously done by another artist or was it an original?
Ever since the first time I heard it (by Pearl Jam) for some reason I've always thought that I'd heard before, maybe ages ago. At first I thought it might have been Joan Armatrading, but searching by that artist didn't turn up anything.
So was this a figment of my imagination? It wouldn't be the first time that I thought I'd heard something previously but was mistaken.
