Turns out the only things you can customize in your profile are your username and the color of your box. This has a double advantage. It’s a real time saver, considering how other networks practically ask you to compile an autobiography for your profile. And it imparts a soothing, Zenlike simplicity to the user experience–all you can do on Muxtape is listen to mix tapes and make mix tapes, nothing more.

You can only upload one song at a time, and choosing your tracks involves navigating layers of folders in a little window. About a third of the songs I uploaded errored out and required at least one more attempt to get them up. Granted, I uploaded the first couple using the latest Firefox beta, which is kinda buggy, but I had similar problems with Safari 3.1. Muxtape is, after all, a brand new site, so it’s to be expected it’ll have bugs of its own.
