I remember that boundary. Well, I was stuck with way less than that boundary; I had 486DX2 66MHz, which was way underpowered to do any MP3. There were software for Windows that could play MP3s at reduced quality. I don't know if I had any counterpart of that for Linux at the time... I've then replaced CPU with one of the AMD upgrade processor (perhaps 486DX 100MHz equivalent or better, I don't quite remember the detail as it was a long time ago), and that's when I could start playing MP3s.
