Imation was once called 3M, by the way.
Music or data doesn't make much difference. The only reason some CD-Rs come with the label Music on them is simply that a ROYALTY is paid to record companies for those discs. There is also a marker on them that lets you use them on consumer CD-R audio recorders. Those stand-alone recorders won't record to standard data CD-Rs because the mark is missing. Other than that, the discs themselves are identical to data discs.
A good data disc is a good audio disc and vice versa.
In fact Imation doesn't manufacture CD-Rs--they have them manufactured with their name on them. I believe their favorite source is CMC Magnetics which is considered the WORST in terms of quality and consistency. Of the various brands I've used Imation by CMC has been the worst. Years ago they had Tayio Yuden make their discs--and I have some of those. Those were super quality. These days it seems they are all CMC. I bought two 50 disc color spindles a couple years ago and every 3rd disc had unreadable sectors near the end.
Also, some drives like certain brands/formulas more than others. I've been pleased with Sony and Maxell CD-R's. Ritek makes many good discs. But Tayio Yuden is usually the best. It's hard to know who makes the discs unless you buy online and you are told who manufactures it. But you can always test your discs with Nero tools--CD-SPEED and see if the quality is high.
Hope this answeres your question,
