Not sure if this has been discussed. I'm curious just how many bass parts were done with a fretless bass on popular rock or metal tracks. By popular I mean more commercially successful tracks. Doesn't have to be a top 10 track but something familiar. To me fretless never really screamed Rock but a couple big ones come to mind. Two that stand out for me are "Mama I'm coming home" from Ozzy's No More Tears album. "Even Flow". From Pearl Jam's Ten album.
