Ok, I was interested in aquiring a MP3 player that didn't make my poor 400Mhz DVSE iMac feel like it was running a race barefoot on pokey rocks.
So here's what I did. I got mpg123, MacAmp Lite and iTunes (Sound Check, EQ turned off, iTunes window closed) and had them all play 3 different MP3's of the same song (Good Charolette - Say Anything) @ 192 bitrate.
To remove as many variables as possible I quit the finder and any and all applications that can be exited without going through the Terminal. I'm displaying my first screen to show all the running processes, then just the applications processes after that with an average at the end, negating the highest 2 scores and the lowest 2. Samples taken by top were 20 every 10 seconds. (top -d -s10 -l20)
Code:

Final Analysis:
mpg123 -- FREE Command Line player.
mpg123 is extremely senstive (read: skips alot under normal use) giving it one sad face, having a unintutive tools gives it one more sad face, but scores up one smiley on low CPU usage.
mpg123:


iTunes -- FREE GUI player.
Being free scores it one smiley face, being a big resource hog scores it one sad face having a great interface scores it one cool face.
iTunes:


MacAmp Lite -- ShareWare MP3 Player
14 Day Trial after which you have to pay $12 to register to continue using it - meh, that's what shareware's about.
MacAmp scores a cooleys in:
low cpu with a GUI. Scores 1 smiley for intutive, non-obtrusive interface for MP3 player, and one sad face for lack of ID3 tag support up to some versions of v2 (either v2.3 & 2.4 or just 2.4 I haven't bothered to check). Either way it's annoying.
MacAmp Lite
