OK, Tony, you pressured me into it...

I would say anything from the re-mastered Rush CD "Moving Pictures". (Got to be the re-master, though!)
There's a CD by Cyrstal Method called "Vegas" -- all electronic music, some pretty amazing bass on it, good production, great clarity.
Finally, almost any CD produced by Sheffield Labs.

Since I am not a rock and roll fan, I am clueless about Tony's recommendations except for two of the Rush songs.... ;-)

Also, I agree with Tony -- you are not going to be satisfied with 128 kbps for long once you get your empeg. The difference in file size between fixed 128 and the Normal-High VBR setting in AudioCatalyst isn't that great, and the sound quality is better. Also, hard drive space is cheap even on an empeg. You may have a really good sound card and speaker set with your PC, but I'd bet that it is really pretty sorry when compared to even a moderately good in-car stereo system. (Please -- no flame war here! I'm just expressing my probably ill-informed opinion, based only on my exposure to a lot of not-very-good PC sound systems! Maybe there is such a thing as a good-sounding system running from a PC sound card. I just haven't heard it.)
