OK, S., this one might not be to your taste, but...
We LOVE Bollywood music! I like a lot of diverse music, world music, stuff with interesting melodies, instrumentation, and rhythm. Also, I tend to listen to lyrics, and if I think the lyrics are dumb, I start feeling very irritated!
So, for my purposes, listening to music in languages I can't understand is good when I want pure motivation from the music without being sidetracked by some trite junk that the song might actually be about ;)!
In my opinion, modern (Asian) Indian music is terrific in SO many ways. Most songs have an excellent, driving beat, unusual and clever/unpredictable melodies, and are great to move to.
I just got a new CD called Dard-E-Disco from a local Indian music video store nearby, and, while I'd call it kind of "sell-out" Bollywood music, since it's been mixed with techno to become like one continuous song, it's GREAT for keeping your energy up. In fact, I've been thinking of taking it to my kickboxing aerobics class instructor to see if she'd be interested to use it.
Other Bollywood favorites of mine come from the Lagaan and Dil Chahta Hai soundtracks, particularly "Chale Chalo" from Lagaan (which is a song about continuing to try), and "Kohe Kahe Kehta Rahe," "Woh Lahdki Hai Kahan," and "Tanhayee" from Dil Chahta Hai.
I hope you can give these a try :)! Might sound strange if you haven't been exposed to Bollywood music before, but it's WONDERFUL, energetic music!
Here's a link to tracks from Lagaan:

Also, I LOVE the music of the Hawaiian group Sudden Rush. It's a blend of Reggae, Rap, Traditional, Hip Hop -- a bit of everything but excellently produced, with terrific quality of voices. VERY COOL!
You can hear some of their music here:

"Hi'ilawe" and "Ride Through Paradise" are two of my ultra-favs.
Good luck with your workouts!! I'm off to do one myself now!
