Thank you for the feedback anywherenotes. Adding the lyrics is a great idea if I can find a public API. I planned to do a song preview using Itunes/Amazon clips on the Movie page but I was having some performance issues. Currently, you can get to #rd party previews via individual "song pages" though I realize this is less convenient.
http://Sweetsoundtrack.com - I often hear music I like in movies and want to add them to my personal collection. This website allows users to look up a movie, and quickly find information about the songs and artists featured in the soundtrack. I started to make a little revenue - enough to cover my hosting costs. I'd love to hear any feedback.
I have a bigger problem with leaving jackets/coats at bars & restaurants. I also have had occasions where somebody took my coat by accident. Just last week, somebody also mistakenly grabbed my suitcase from the overhead compartment of an airplane.
Assuming this would work just as well for non-wallets, I think this is pretty cool.
Ever since I saw this guy's project, http://www.sotmclub.com/, I've also been racking my brain for other ways to leverage this model.
