Online Radio Addictions

What would I do with out Pandora and LastFM? Both of these online "radio stations" make sitting at the computer for hours on end a joy. No commercials!? The music I love!? FREE!? Yes, please. Both sites have a variety of similarities and differences and I've found that it really depends on my music mood as to where I go for tunes. The best part about both is that I've discovered so many great musicians that I doubt I would have heard of other wise. Next time you're stuck at the office and need some background noise, skip the Top 40 station and check out either of these great sites. To get started try the Sufjan Stevens station on LastFM or Laura's The Submarines station on Pandora.
