I’ve been listen to the radio using both my Playstation Portable and PC using the stations available from .977 Music Portal.
The Classic Rock Channel is the one I’ve been listening to the most recently. They play the greatest rock from 70′s with the occasional 80s mixed in for good measure. If it rocked in the 70s, you’ll hear it here. From AC/DC to ZZ Top.
As these are commercial channels, you do get the occasional advert in between the tracks, but not every 3 minutes!
