So, in essence, it is no longer really Muxtape, but an entirely different idea that is just a nod towards what it started out as. This may not be all bad for Muxtape, but it definitely goes to show two things:
1. The major labels/RIAA are far too stiff and don't seem to understand how to work with websites for their own profit. If they had worked out a fair deal, this could have undoubtedly be incredibly profitable for both Muxtape and the labels.
2. Attempting to do something like this will take either a bigger backer (more money), or for the RIAA to suddenly gain an understanding of the internet's true potential.
Regardless, it is a bit disappointing that Muxtape is no longer Muxtape -- however, there are imitators out there working to provide a similar concept, and one of those might just succeed. This has just been a jumping-off point for a lot of people...even if this one doesn't succeed, it's made its mark.
