This week, this isn't just one song, it's a whole bunch of songs! Found in the comments section of Roni's Weigh was the URL for the new site Rock My Run.

Wow, what a great resource.

The site is still in beta, but it seems to work just fine. And since it's not officially open for business, you can download fantastic mixes for free.

So far, I have downloaded two: Every Moment Counts, a 30-minute mix of house, pop and hip-hop mixed to 140 bpm; and The Get Up, a 60-minute mix of pop and hip-hop at various bpm.

And because of those great mixes, I wogged (walk/jog) 6 miles on Friday -- I never do that. Even better, I went to the gym yesterday and ran pretty much all of my 2-mile workout.

Here's a cut found on The Get Up -- Boom Shake Drop. Something from down the street in Miami, with DJ Laz, Pitbull and Flo Rida:
