I dont know if I raved about this on metabeats before but I have to reopeat myself if I did...
You should check out paradise radio.....its on itunes radio under eclectic ...we play it all day at the office somedays and it is most incredible...They do what good radio should , which is mix music from many genres...country, rock , folk, alt rock, electronic and from the 60's to today. They also dont play just the hits, they pick the good but obscure album tracks that you never hear on commercial radio , mixed it with more well known tracks. For example last hour they played tracks off U2 unforgettable fire, Bob Dylan, blood on the tracks, Neil young , after the goldrush, the new , new pornographers, Elliott smith, some Beck off sea changes , ray charles , patsy cline, etc.....and a bunch of new bands I didnt know...generally they dont rock out hard, which makes it good for the office....
