converting songs to mp3

haemphyst .. I use Exact Audio Copy.  It is the recommended ripping software in the guide I posted.  It is not perfect, but has churned through a few old and beat up cds better than any other ripping software I've seen.  

I also agree with you re: Lite-On and Plextor.  They are the reliable choices in optical computer drives. 

mp3 is _fine_ if recorded at a high enough bitrate >256kbps. 

It is not, however, ideal.  Ever.  mp3 is a lossy format and quality will ALWAYS degrade from the original.  Every time.  On a good stereo you will hear the difference. 

Since it IS more convenient to use mp3 because of storage, people do.  Furthermore, since 99% of most car systems, mine included, are not that great, you probably won't tell much of a difference (if the bitrate is high >256).  Just know and remember that it is not the same as CD and is less than ideal. 

I'll hook up an mp3 player when I'm in a hurry or just want to listen to something not caring about the quality (rap/r&b/pop).

If I'm looking for the best quality, however, and I care about how it sounds, yes, I do keep the CD in the car.  (usually my jazz/classical cds). 

To sum up:

1)  If you want the best quality use the original CD. 

Again, if you can't hear the difference either you've already cooked your hearing or your equipment is not good.  Might be both on DJ equipment.
