Online Radio and Music Rocks

Getting sick of your same old iTunes library? You can legally listen to tons of new music free by checking out best online radio stations and streaming music sites--all you need is a computer (well, and a pair of headphones if you don't want everyone at work to discover your secret love of polka). iHeard is a search engine for free music, sports, and talk radio (filter by genre, country, and language, or see what's most popular). RadioTuna gives you free real-time search and profiles stations by the music they actually play (not the categories they list themselves under). Pandora creates your own personal radio station based on music you like. Grooveshark is like a web-based, pre-loaded iTunes--search for songs and create your own playlists. Last.fm is a super social site that lets you find music you'll like based on similar users' recommendations (you can download free MP3s, too). AccuRadio has over 430 channels to choose from and Live365 has over 6000 stations...but if that super-specialized content isn't unusual enough for you, RadioBeta specializes in international stations. Finally, NPR's not just a lifesaver for your commute--you can also listen to its continuous stream online, 24 hours a day.
