How macs and pcs gather their information for commercial cds

[dylanfowler1]

I'm trying to get some information regarding a problem I'm having with the correct cd information being found when ripping a commercial cd.
I run a small label and with a recent release the information taken from a cd put in a PC is correct but the same cd put into a Mac shows an incorrect spelling of the group name. Initially we thought the problem could be with the cd but having downloaded software that reads the info directly from the cd when placed in a PC and seen that it is correct - the problem must lay somewhere else.
Any ideas??

I think the mac gets its info from iTunes store or the Gracenote site
