Like the headline says. Here are some songs about (or addressed to) singers.
"Steve Earle" - Lydia Loveless
"Johnny Cash" - Madeline
"Rickie Lee Jones" - Fire Island Pines
"Diana Ross" - Freddie Gwala
"Cathy Dennis" - June & The Exit Wounds
Four of those five titles also appear in the "Artists" menu on my iPod. This woman is the odd one out.
