mp3 player + IM on 400Mhz CPU

Ok, I started a thread here about using a 400Mhz AMD-K6 2 based computer (with 640MB 133Mhz SDRAM + a GeForce 4 128MB AGP) for video streaming purposes some weeks ago.  Didn't work out.  Needs moar megahertz.  However, computer seems totally usuable for something, just don't know quite what yet.

So I'm installing Windows XP on it.  So far so good.  Right now I'm installing basic stuff on it. 

For web browsing, I installed Opera, and it's fuck fast on this shitty CPU compared to even IE.  Makes it almost look like I'm using a reasonably modern computer.

I was wondering what Anonymous suggests on a machine of this caliber for the purposes of music playback and instant messaging.  Can't use Pidgin because it crashes.

installed win2k on that and you are good to go nigga
also how much ram you got in there is a factor too
i had 96mb of ram on a 400mhz celeron back in the day and it was good enough to play diablo2 and mp3s at the same time
