Like already stated, most CD players only read CD format disks and not DVD. You need to compress your music files to get 90 minutes on an 80 minute cd format. What file type format are they in? What program are you using to burn the cd?
I got tired of making cd's for my truck so I bought a new stereo for my truck that has a USB port and I run a USB powered 100 GB portable hard drive in my truck and I have about 400 or 500 full CD's stored on it. The head unit allows me to browse or search the library. I can also build playlists. When I want a change, I take it out of my glove box hook it up to my computer and change it then put it back in the glove box and presto new music or playlists or whatever. Plus it allowed me to now store all my music on the portable HD and not on my computer. I do have it backed up on a second HD in the house though which I can access through my playstation3 which is hooked into my home theater. I like music
