Quite an old quote, but I had to do it!
I'm using D-Fend Reloaded myself and it is a quite easy to use frontend for DosBox!

I figured out how to get the CD music to work from the primary download. The only "bad" thing is the "waste of disc space". Shouldn't be a problem on todays systems...
The size of the game increases to around 327MB.
In D-Fend Reloaded you got a VrtualHD folder. I copied the game to
.\VirtualHD\GAMES\ALONITD1\
This means, that I had to edit the "INDARK2.CFG" with notepad and put the path "\GAMES\ALONITD1" into it.
I copied the \CD folder into the \ALONITD1 folder. Now here comes the trick:
I converted the .MP3s located in the \music folder to .WAV files and copied them into the \CD folder overwriting everything! To convert the files to .WAV you can use the "Disk Writer" plugin in WinAMP or the "WAV Writer" in the output setting of XM-Play. It's just that easy!
After all that I configured the game in D-Fend and mounted the .CUE file as as drive D:. Started the game and it works with the "high quality"-CD-Music! YAAAY!
PS: I've read the first 12 pages of this thread and nobody mentioned this. Sorry, if it was already known to do it!
