Simple Mp3 Player, as the title states, is a pretty simple Mp3 player for mIRC, it's main attraction is it's ability to set the song your currently listening to as your MSN personal message (Compatable with MSN 6+). I had a few people asking if it's possible to set a custom directory so you don't have to browse from your mIRC directory every time, there's an option in the 'File' menu. The script requires a DLL to work with MSN, this DLL will automatically be downloaded upon loading the Mp3 player. This is a one-time download unless you lose the file.
EDIT: Functional playlist added
