Interesting article, but a bit suspect. I think probably the difference between "Deep Tracks and KSHE is that "deep tracks" is a secondary stream similar to KSHE2; you need a digital radio to pick it up, and KSHE (which is listened to world-wide) is the main feed, and KSHE2 isn't streamed. Your link says "A great deal of care went into the "Deep Tracks' station, making it one of highest quality rock stations in America. the music was locally programmed and carefully selected. DJs were used to give greater insight into songs and deliver a better listening experience. Most recently, the DJs used were local rock radio veterans Seaver and Byrd"; no different than tonight's show on KSHE.
Tonight you can hear Journey - Departure, Joe Walsh - So What, Steve Miller Band - Book of Dreams, Def Leppard - Hysteria, Blind Faith's only album, and Pink Floyd - Wish You Were Here. They play the whole album uncut and uninterrupted without a disk jockey talking over the music.
Oops; that was last night, being retired I lose track of what day it is. They haven't announced next week's yet.
So I suspect "deep tracks" is in trouble not for the format, but for streaming their second channel. Also, the RIAA and ASCAP collect higher fees from streaming than broadcasting, making that article look even more suspicious.
