==================
Most of that is from memory, though I have about 2TB of music on my home PC which I've managed to stream to my phone. But having such access, I can find a lot more "One Hit Wonders" than just memory could provide. If pushed to name my top few from that list:
Robbie Robertson - Broken Arrow
Uberzone - Moondusted
Modern English - I Melt With You
Golden Earing - Radar Love
Eric B & Rakim - Paid In Full
