I think now lots of people are using f2k for playing their music. I'd suggest adding to "how to playinfo" at the main site link to plugin foo_dumb. Can be found here. It played major part of pack for me. Try it out and forget about winamp and XMplay. IMHO.

Update:
You'll need also from site above:
Hively Tracker Decoder (foo_input_hvl) for playing *.ahx files
Midi module (foo_midi) for playing *.mid files
and
Game Audio Decoder for playing *.sc68 files

However i can not find a way to play *.mo3 *.ym *.sm2 *.v2m...though they are in minority. Again IMHO it's better to convert them once, than stick with yet_another_audio_player.

P.S. Cool DB!.

Sounds good, but anyway XMPlay has the best quality for playing tracker modules. If there's plugin for foobar based on BASS.DLL then it will have about the same quality

I don't agree. In my opinion, Winamp has much better quality than XMPlay.

Well, you won't find so much settings in Winamp for tracker modules Winamp uses MikMod-like engine - it has not much post processing. It's possible that for your preference it's better but generelly/usually XMPlay has best quality and ModPlug or Winamp on 2nd place and just MikMod-based players on 3rd place.

I agree about XMPlay, i used to have DeliPlayer but it's too outdated. XMPlay plays all files i have (of course using dlls).
With winamp i find it hard to 'jump blanks' in a track.

OK OK, don't kill me
