Sorry, I'm back on the radar now.
Someone uploaded a new version with Dreamcast CD-DA audio added for UT. UT4 music has also been ripped. In addition, sound effects have been perfected with the effects from the UT3 demo, Unreal Engine 3 SDK & Demo kits, UT4, and all the new Unreal betas that were found (from the 2013 Emissary/X-Com Alliance dump). New remixes have been added, too. But the biggest change by far is the addition of all unused patterns from the tracker files. Ones that formed a sequence have been added as complete unused subsongs too (as in, the files were literally edited in Open-MPT to string them together). A few songs had some very interesting cut material (UnWorld2 from UT, Twilight from RTNP, Bluff Eversmoking from Unreal, etc.).
