How obscure are we getting... some of these are obscure for a reason, lol.
Free, "Mr Big" off Fire & Water
The Modern Lovers, "Pablo Picasso" off The Modern Lovers
Blue Mountain, "Let's Ride" off Dog Days
Grant Lee Buffalo, "Mockingbirds" off Mighty Joe Moon
Hanne Boel, "Still Shines" off Outtakes
Ruston Kelly, "Blackout" off Dying Star
I dont know how obscure these are but they're no Saitisfaction, Purple Rain or Walk This Way... just my opinion
