There are a handful of artists whose music consistently curries favor with folks in the gym. Cascada and Flo Rida--both of whom turn up in this list--come to mind. But, Pitbull is the first to have two songs simultaneously voted into one of our playlists. Accordingly, you'll find Mr. 305 checking in with his ubiquitous "Hotel Room Service" and again, with Baby Bash, on "Outta Control." (In keeping with Pitbull's habit of mixing English and Spanish, I've replaced Shakira's "She Wolf" below with her Spanish version.)

1. Pitbull - Hotel Room Service - 126 BPM

2. Demi Lovato - Here We Go Again - 142 BPM

3. Shakira - Loba - 122 BPM

4. Flo Rida & Nelly Furtado - Jump - 130 BPM

5. Sean Paul - So Fine - 137 BPM

6. Amy Winehouse - Rehab (Hot Chip Remix) - 145 BPM

7. Gossip - Men In Love - 132 BPM

8. Cascada - Evacuate The Dancefloor (Radio Edit) - 126 BPM

9. Jay Sean & Lil Wayne - Down - 132 BPM
