Although in almost all cases 128kbps is just fine and you couldn't tell the difference.
As someone who eagerly pays extra for FLACs when given the chance, I'd rather a poke in the eye than a 128 kbit/s mp3.
EDIT: Just to preempt the righteous nerd-anger crew, I'm aware that higher bitrate MP3s are transparant; I value the bit-for-bit archival of the original record that flacs provide.
Cymbal wash is enough for me to never pay a dime for 128 kbits tracks.
You are probably both if you really believe that.
