Not necessarily. There are some CD players out there can play mp3 files off cds. Theoretically, you could probably fit over 150 mp3s on one cd. That's quite a few albums

HEY! MY TOPIC! MY RULES! ;D
I actually have a reason for asking this question, that is why I wanted one cd , I guess I should have specified no "homemade" or MP3.
I personally would prefer my MP3 player because I have over 200 CDs ripped into it.
But what I want for a answer is one (1) CD, record company produced album, "double albums" count as long as they are packaged for sale as so. (My choice for example) No box sets! No MP3 cds!
And before the question arrises the CD player is solar powered

After my little survey is done I'll explain my reasoning for asking this question.
Thank you for your help!!
