YouTube / Last.fm Mashup
Many artists and labels post official music videos online. This YouTube/Last.fm
mashup will try and play back the videos to the albums and songs you request. It does that by searching Last.fm for music data,
and at the same time searching YouTube for appropriate videos.
Unfortunately, the whole thing is built using Google's toolkit for webapps,
which translates Java code to JavaScript code running on the browser and also facilitates communication with the server, which
is also running on Google technologies.
JavaScript only :(
Consequently, the whole thing doesn't do anything unless your browser supports JavaScript (and it's enabled). Sorry!
For what it's worth, here's a screenshot of it in action:
