The Top 10 Everything of 2008

The all-time best free app for music lovers. You pick a song, album or artist and Pandora immediately builds a whole "radio station" around it, endlessly streaming complete tunes from top artists. You can even tweak your station by giving songs a thumbs-up or thumbs-down. Music quality is amazingly good for audio that streams for free over AT&T's data network. The music library is solid for genres ranging from rock to pop to jazz to classical. It really needs African music, though.
