Hi I just bought a Custom CD off Walmart Custom CDs site. I thought well I can make a custom cd plus watch my money and hey im geting what I wanted. The thing I am woundering is am I paying for mp3s? or Waves? When I get the CD it works in my everyday CD player and it sounds ok I think? what I mean about that is I feel like mabie i'm listening to mp3s. Some songs sound different meaning worse then my mp3 copys like your think my old mp3s sound better. I went on FAQ on site and it claims only as they will work on CD player. What I am trying to figure out is are they giving me MP3s just burned on a cd? The only reason is I thought I could make lossless audio of these when buying being they are lossless audio. I thought this would sort of fit here in general audio since its a general audio type question.
Thanks

Though I am not familiar with their service, you can test the spectrum of the audio on the disc yourself and look for tell-tale lowpass.
Alternatively, there is a program called
Tau Analyzer by The True Audio project (makers of TTA, a lossless codec), that does just that: it tells you whether your CD was most likely made from lossless or lossy material.
