So as far as intentions go, this website is a way to facilitate the trading of mixtapes with friends or other people. There's a bunch of forums that link people up to share mixtapes or cds but they all require a user to mail the mix to the other person. This kinda makes it local, so the more people in your city to sign up and use the site the better. We did get the idea for the site from geocaching and sites like "Where's George?". Another use for the site was we wanted a way for local bands to promote their music by giving away cds. We were going to implement something where a band could burn a bunch of copies and get a special ID that shows up with a different icon or something and maybe let them have a little advertisement page. We didn't have time to implement all the features we wanted before the deadline was up.
As far as copyrights, I suppose that for the duration of the class any mixes made with copyrighted music would fall under fair use. After that though, as stated in the user agreement, you would need to either own the copyright to the music (like, if the mix is music from your own band) or use free music (such as creative commons licensed music). People have been making mixtapes since the 70s with copyrighted music however, so I don't know all the legal aspects of making them. One of the guys in our group made the point that if someone wanted to use this site to commit copyright infringement, it'd probably be the least effective way to do it...
Interesting topic... Anyone else have opinions?
