So I recently got a new job where I can listen to music during the day and immediately thought of getting an internet radio app for my phone to supply me with an endless supply of tunes to get me through the day. The only problem is, I don't know which app and service to use. I have tried out pandora radio and last.fm and so far I like last.fm the best because you can skip as many times as you want. It seems to me that among the forums pandora radio is a favorite though. Is anyone educated in these three services enough to tell me the pros and cons of each? Like I said, I like last.fm because I am not limited by the number of skips I can have per day/hour like pandora and slacker. What does everyone suggest I use and why?
