any computer guinesses on here?

my truck plays the CD's that I make from the songs I download. The songs have mp3 endings in there title, so I know it works.
The question and explaination is (was):
I have every Beatle album that was released in the UK, USA and Canada except the White Album. (and I do not count any of those copilations like Anthology, ONE, or whatever).
The problem was that I downloaded all the songs that were on the White album so I could make a CD and complete my Beatle set, but the songs are 90 minuts long. Too long for a regular CD. So I had to put them on 2 CD's.

Ok, there are two "popular" ways to play music from a CD. The first way was a .wav file which, for the most part, is a lossless format. Meaning the music wasn't compressed, it's just a straight digital recording. Those files are going to be rather large given they're not compressed, so when you'd buy a CD from the store, you'd only get 60-80 minutes of music, max. FF to the internet music boom and you have the popularity of MP3s, which were created by "ripping" music from a store bought CD (that consisted of .wav files) into smaller, more downloadable, compressed files called MP3s. These were much smaller than the current .wav files and therefore, when burned to a CD as MP3, not .wav, you could fit about 5 times as much music cause it took up less space on the CD.
So now, we need to clarify...does your truck play .wav files or .mp3 files? Just cause you burn the MP3 file to CD doesn't mean you'll end up with MP3s on the CD. Most CD burners convert the MP3 to .wav if you tell them you're burning a music CD. To burn MP3 files and keep them MP3 files, you need to burn a data CD.
If you burn MP3s to a CD as data, you should easily be able to burn 4 "sides". When you try to burn MP3s as music, you're going to hit the problems it seems you're currently encountering.
