A couple of weeks before Christmas I got a mail from The Echo Nest developer team promising a free T-shirt for filling out a survey :

Survey Email

I didn’t expect that they’d send a shirt all the way to Australia (plus I thought I’d probably missed the cutoff), but they provide an amazing service so I thought I’d fill out the survey anyway.

A couple of weeks later, lo and behold, they came through with the goods!

If you have any interest whatsoever in music programming, I can’t recommend their API enough - they are doing some really incredible work.

Update : I’ve put up a couple of remixed videos, in case you’re wondering what kind of stuff the API allows you to do.
