Hmmm...Still working this out...
When I last did a radio show, we had like 3 hours and change to do a show. I played a pretty good mix too, but it was a year or two ago, and I'd also have to change what I put on...
Start with some obvious ones for me:
Jaye Muller--Come Over Here (Remix by Nuno Bettencourt) (Even though I'd really love to play Savage or Starshine, but I can't for...Reasons...)
Guster--Eden
Dar Williams--Are You Out There?
Ra--Rectifier
Tribe of Judah--Suspension of Disbelief
Nuno--Spaceman (Or stiff, depending on the mood)
The Stone Coyotes--Plain American Girl
Aimee Mann--High on Sunday 51
Screw it. I'd improvise the rest.
People tuning into me would have to suffer through everything from folk, metal, jazz, and the occasional pop acts (I played 5ive's WWRY cover live on the air...

)
