Hiya! (I'd post a link, but I'm not sure if I'm allowed to do that?) Podrunner Intervals are free, varied BPM electronic music mixes-- lookup djsteveboy.
He has hour-long mixes at certain BPM and now the intervals, with varied BMP and chimes to let you know when to step it up or slow down. Different mixes for each week that follow a couch to 5k type format, also one for 8K, 10K...
I love the mixes. Pretty much all I ever run to when I'm on the treadmill. Outside, I can run without music, but on the hamster wheel-- must have podrunner
And they're free! Did I mention that?
p.s. Of course, if you hate electronic music, you won't like it!
