Great app if you have an extensive library! – jog.fm - Running music at your pace Review

I have a pretty extensive library on my iPod, and this app has helped me find music for my workouts. As another reviewer noted, it won't suggest music from jog.fm or other sources, but it does a great job of identifying the beat rate of your existing music and matching it to your pace (either by detecting your movements or by using a set minutes/mile rate). I like that you can tag music as favorites and also blacklist it from your workouts (a great feature if you don't want all your Christmas music to start playing!). I found the app to be a bit slow at times and wish it had a button for restarting a song, which is the only reason I can't give it 5 stars.
