Most of the time iPod, iTunes, MP3's! *Not* OTA Radio!
If it has to be radio then it's WLUW 88.7 - too bad they don't have metro signal coverage! WONC 89.1 Pure Rock is also a good choice.
I am not fond of commercials - yeah, I know they 'pay the bills' - how about charging more for each commercial and having less minutes of commercials per hour?
