These are DTS WAV files.  I ripped them from a CD image since I like
to have songs each in their own separte file for making mixed CDs
and playlists.

To play them, it's best to use DTS hardware, but still amazing
when you just play them on a normal 5.1 system with software
that supports DTS decoding like VLC or foobar2000 with dts addon.

If you want to burn them to CD, don't recode them in any way, just
rename the files from .dts to a .wav file extension and burn. The
.dts is just to let software know that it's a DTS file so it software
decodes it.  This allows you to play it even if you don't have DTS
hardware.  Great for people (like me) who have a 5.1 setup, but
don't have DTS hardware.

As for the source, I got it from a torrent.  The torrent said:
==================================
This is from a STEREO source which has been UPMIXED
to 5.1 DTS Surround Sound.   The Stereo Source used
for this Upmix was - 'Blondie - Greatest Hits (2002)'

*This is NOT an official DTS release*
Blondie - Greatest Hits (5.1 DTS Upmix)
