I'm more of a sports guy so I listen to All Night on ESPN radio. Sometimes i'll throw on some old lovelines form lovelinearchives.com
"When Radio Was" has old radio shows (the kind with actors like a tv show on the radio...yes, i'm younger than that generation so i don't know what they were called
). Thats on KIRO 710 here in seattle all night
short of those its all conspiracy type of things like "Coast to Coast"
