My car radio stays on Deep Tracks 95+% of the time. I have a self-seeded Deep Tracks-like Pandora channel I listen to in my home office and in my wife’s car via streaming it from my iPhone.
Tom Petty’s Buried Treasure reminds me of some of the things Detroit DJ’s could do with their station’s libraries. I remember a program called “Seventh Day” on either WABX or WWWW (W4). It featured 7 albums, back-to-back, every Sunday starting in the afternoon and ending in the early evening.
