according to my own experience with a Sony car stereo, I strongly recommend reading the appropriate chapters in the manual, as there might be some conditions that must be met in order to allow proper playback.
Do I create a set of folders in Nero before I burn that have categories of music like a Jazz folder, a Rock folder, and a Oldies folder and then dump the appropriate MP3 songs into the folder?
This should work. I am using CDex for ripping my CD discs to mp3 format. It will create folders \artist\record\ an put the tracks there. The track names are like this: 01-title1.mp3, 02-title2.mp3 and so on.
Optional: You may adjust the ID3 tags according to your needs and the requirements of your player with some MP3 tagging software, I use mp3tag (http://www.mp3tag.de/en/download.html) for this job.
Then burn the disc as data CD, you have to adjust the settings of your burning software properly (Again, see the instructions given in the manual of your unit). Nero Express offers a preset “mp3 CD”, maybe that works, too.
I’m assuming that I can then select the folder and it’ll stick with that type of music until I switch to another folder manually?
It should work like this. Or your car stereo offers some “random playback” mode or similar.
Beleive it or not I don’t own an iPod so this is a little new to this old fart.
I don’t own an iPod either as I have no need for that
