StumbleAudio is your new music discovery best friend. The site is like StumbleUpon, but for tunes.
Without ever having to sign up, you can check out over 2 million different tracks based on your genre of choice and the ratings you give each stumbled to song. What’s different about this site from other such popular sites as Pandora and Jango is that you can actually listen to each full track on an album in order without any extra leg work. If you want to look for a particular artist’s sound, they’ll provide you with a list of albums that sound similar to what you’ve entered. From there, you can stumble your way through the various search results, giving the thumbs up or down to each given track, helping to guide you right to the songs you are looking for. Once you’ve found a tune you want to hold onto, you can go to purchase that mp3 or album from one of the various sources they list with each of their various prices included to help you get the best deal. They also give you recommendations by artists you are less likely to know, instead of the typical pop stuff you could find easily on your own. If you do create a user account, StumbleAudio will save your preferences, and you’ll be sure to get to a tasty bit of sound much quicker the next time you visit.
StumbleAudio.com In Their Own Words
“StumbleAudio is a social music discovery site with a mission is to help you find music by new and exciting artists that you would like, rather than play or sell you the hits by known artists that you are “expected” to love.
Our catalog has over 2,000,000 tracks by over 120,000 artists ready to be played in full length, high quality, free of charge.
StumbleAudio started to build its recommendation engine by importing massive anonymous data of saved favorites, music preferences and buying patterns from several online download and actual music CD stores. As you use StumbleAudio the system learns from your “thumbs up” and “thumbs down” and constantly adjusts the music offered to your liking.
We are committed to making our recommendation engine more accurate and relevant as we collect more real use data. We will also soon have various social network applications and widgets to share you music discoveries with your friends on Facebook, MySpace, Blogger and others.
P.S. And, yes, artists do get paid when their songs are played on StumbleAudio.”
Why StumbleAudio.com It Might Be A Killer
The site is clean and easy to navigate, all parts to the page pointed to and defined as soon as it loads, so that you don’t have to mouse around trying to figure out what each little icon represents. They’ll be able to make a profit from sending people over to buy the mp3s from the various sources, and the fact that you can listen to an entire album right from the site may lead people to actually spend a little more and go for that entire sound experience.
