Muxtape is “a simple way to create and share mixtapes”.
It’s goal is to bring back the joy of laboring over a mixtape for hours to get everything just right, and does so by only letting you create one mix per account, and limiting your mix to just 12 songs. (Each no larger than 10 megabytes.)
When you’re done, the music is then streamed through your browser, so it’s not exactly a file sharing service, but since the only way Muxtape prevents copyrighted music from being uploaded is with a meek little warning: “By uploading a song you agree that you have permission to let Muxtape use it.” I’m guessing Muxtape is going to be dealing with a few high priced lawyers in its near future.
Regardless, it’s a nice (and simple) service that has some potential to help undiscovered artists get their start, and it relies on the “sharing is caring” motto, so I hope some sort of agreement is made to keep Muxtape around.
