I'm totally lovin' this new music site that I've found....Pandora.
I've found so many new artists that I'm falling in love with. The best part about it is the fact that you can create personalized radio "stations" based on songs or artists that you already love.
The site has songs and artists catalogued by certain musical styles, such as "mellow rock syncopation" and "acoustic sonority," and sounds, thus comparing your favorites according to the "musical genome" of each selection. It really makes for great background music, plus if you are so inclined, it links you to iTunes or Amazon where you can purchase the music.
