Different brand CD-R's tend to have varried results on different brand drives, though some discs might just be crappy altogether. So if you could find some tests results for your CD writer model, that would be best. I found a lengthy review on cdfreaks.com for my drive with very helpful graphs.
Taiyo Yuden's are usually known for being of very high quality, especially for use with Plextor drives, from what I've heard. But they do not test well with all drives, like my Lite-On for instance (to the surprise of the cdfreaks reviewer). Ritek and Prodisc are also seem to test well and be high quality discs, and they can be purchased for near dirt cheap from meritline.com
But I agree that you should look around on cdfreaks.com, read reviews, etc. Also maybe try searching Google for your drive model and see what comes up.
I should also note that, as far as I know, the type of music you are putting on the disc does not matter. Rather, as far as I know, certain brands will not be better suited for classical music.
Also, you may find it helpful to know that its usually not recommended to burn audio at a speed above 16x if you're going for best quality. Just thought I would mention that.
