Jason Freeman has developed this nifty web app (thanks to Waxy) which analyzes your iTunes library and creates an audio ‘signature’ (I might have picked a different term for that–omnibus? summary? abstract?) of your musical tastes. It’s probably not very interesting to anybody else, but you’ll find your own signature kind of nifty.
Here’s my signature–recognize any songs? I spotted a few. The application shows you a list of the songs it picked to build your signature, so you can compare. For the geeks, here’s the technical explanation (PDF) of how it works.

Hmm,
While it sounds interesting on paper, in practice, it just came off as too much ear garbage. Too mashed up for my liking. Interesting concept though – I think if the choruses of the songs were distinguishable for more than 5 seconds, I may have liked it more.
Although I did hear Coldplay near the end. What? No Run DMC? Shame…. 😉
Reminds me of the opening to the movie Contact.
I think the idea is that it *shouldn’t* necessarily be directly identifiable (though I could tease out Sarah Harmer and the Tragically Hip, among others). What I did get is that you like, (a) acoustic guitars and, (b) folk-poppy female singers. Very Canadian of you.
Wow, that’s impressive. I just set up my signature and it nails it: in comparison to yours, it’s much bluesier, with crunchier guitars and more aggressive drums, a bigger share of ye olde classic rock (Bowie, Beatles), and a fade-out of “What I Like About You” by the Romantics, which does count as one of my favourite songs ever.
I wonder. I just ended up trying it out, and the signature was of cosmic relevance. lol. maybe the stephen hawking ebooks combined with Hitchikers guide in my library had something to do with it. 🙂
