Muxtape is one of the Web's cooler corners. The simple site, born last month, lets users post a single mixtape of 12 songs. Your tape -- ever evolving, if you wish -- exists as a simple link that you can send around. For an example, see founder Justin Oullette's.
Ouellette came on our show last week to talk about his creation. Muxtape is growing fast enough that he's having to build server capacity sooner than he expected. It's also drawing attention from copyright lawyers, some of whom say what he's doing could pass muster and some of whom say he's heading for a Napster-style shutdown.
