StumbleAudio allows you to listen music 24h/h selecting a genre (e.g., Blues, Country, Jazz, Rock). You can skip the songs if you don’t find them to your liking. Another great feature is that once you find an artist that you like, StumbleAudio lets you listen to an entire album. You can rate songs via a “thumbs up” or a “thumbs down” system, which helps the site determine other artists and tracks that may pique your interest while you “Stumble.” While all of the music you listen to on StumbleAudio is free, there are links to purchase individual songs or entire albums (via iTunes, Amazon.com, etc.) on the right. Registration not required.
