Running interval mixes

Hi everyone,

I just started doing jog-sprint intervals a couple of weeks ago and I'm absolutely loving it. I don't necessarily want to take my phone when I go running, so I currently just check my watch to roughly time the sprints. I've tried out one of the interval mixes from podrunner.com on my mp3 player today and they're quite useful - they bleep and play faster music for the sprints. But I really don't like the music, as it's pretty bland house music... not very motivating.

Does anyone have any links to any other interval mixes (between 30 and 45 minutes) that do the bleeps for sprints? Anything goes! :)

Thanks!
