Very elegant. It's like the soundtrack to my, um, friends' lives.

Little fold-outs that reveal the text that accompanied each post/mp3 would be handy. Also, being able to save tumbltapes to a favourites list would be nice.

A couple of little bugs. First, it had the same track three times in the playlist, possibly because of multiple edits to a single post. Second, it didn't do a perfect job on extracting the band and track names on some of the songs. Both these bugs are demonstrated here: http://www.tumbltape.com/audiographical

Really good work.
