MP3 Compressor

Anyone know of any such program which can resize your .mp3 file?
If you've any please let me know. Thank you thank you. =))

why do u wanna compress a compressed file further?

if you compress even more, you will start to lose sound quality of the song liao.

You should at first rip into WMA, not MP3. WMA is smaller. Much smaller. Or maybe from CD rip into Ogg.
