I can't release as a mod as I don't own the rights to all the music, and don't believe it would be kosher to distribute in that way. That said, all of the music I used, allowed for the type of use that I made of it, with mostly creative commons licensing provided attribution was made. I did include a list of all the music that I used in the Piratey Music mod in the description of my videos.
This is the Music list from my last vid:

As general information, for the tracks that tend to loop (Geoscape and battlescape) I tried to mix tracks with 3-4 songs, that were up to 10 or so minutes in length. Most players can finish missions faster that I did while commenting, so I think that length was probably about right. Shorter tracks in my experience could get a bit repetitive.
