There's a CD at Hallmark called Cardio Pulse, which is a CD of ABBA hits remixed to a good workout beat.
I've also been listening to the latest Juanes album. It's Latin but he sounds pop to me. I don't know the translations to all his songs, but I love the beat and I'd rather try to figure out the spanish words to the songs in the middle of a workout than figure out how many minutes I have left.
And lately I've been listening to the Lady Gaga cd, for the beat.
I went last night for the first time in a while, and boy, did it feel good! Granted, I still have not yet located my ipod, but I've gotten most of the tracks you ladies suggested, and they are fantabulous!! thanks so much!!
