I don't know about the 'stereo component' CD-R/RW devices but my CD-R's in the PC's don't complain one bit about writing music to a data CD (although I can't speak for the newer ones). I don't think I've ever bought an 'Audio' CD-R ever, and judging from the amount of shelf space they get at Staples, I don't think most folks do.
