On the old A3000D I had (with Commodore's 040/25 accelerator) I used to first copy the MP3 to the RAM disk then run MPEGA to play them over Paula. It went quite well on 96kBit MPEG3s. I also had to increase its buffer-settings to fully load the MP3 into the buffer. I was never fond on using the Amiga clones of Winamp as they seem to suck up all the CPU power for their GUI's.
