These modules are not original Chris Huelsbeck's. If you wonder why, it's because Chris almost always coded his own formats.
In game Turrican 2 "format" is called Seven-voice routine or so.
These modules (other people's remakes) you are about to download are quite bad compared to the original and doesn't sound like the original (few exceptions come close though). I've ripped Turrican 2 music in digital audio format (using stereo-mix method) from original game on WinUAE Amiga Emulator.
I suggest you to do the same if you really want Turrican 2 music.
!!! EDIT (following text was added much later): you can however get the *original* Chris Huelsbeck's modules in his proprietary TFMX format at: http://www.exotica.org.uk/wiki/Chris_H%C3%BClsbeck
including also all of the Turrican (1, 2 & 3) tunes! Only thing you need is a TFMX player. There are few really good ones available as a Winamp plugins!
(the original Turrican tunes would of course get maximum 10/10 rating!)
You can also get great Turrican remixes (in MP3) from www.AmigaRemix.com just go here: http://www.amigaremix.com/remixes/search/turrican
