I hope those are copyright free titels.
Since mods can only use self produced tracks.
And the
633 Squadron main title by Ron Goodwin (loading music for Operation Hyacinth) is copyright free?
Duration is in the EU 70 years after the author's death - even though using a MIDI/tracker/whatever arrangement and self-sung vocals would get you around the performer's rights - and Goodwin died in 2003.
Seriously, I would like to hear "Panzern rollen in Afrika vor" promoted from a radio tune to a loading tune of a map. Plus, German version of "Lili Marleen" (also still copyrighted) would also be very welcome.
In the 2.2 and beyond, "Watch am Rhein" (free) could be interesting. Or "When Johnny Comes Marching Home", or any of John Philip Sousa's marches (also free).
Yes, I know that Pacific might never be done at all, but if it is, then I vocally demand "The Ballad of Rodger Young" (still copyrighted, but see above) - "The Marines' Hymn" and "Semper Fidelis" would be too obvious to even suggest
Even though movie soundtracks might be tempting, they do have the copyright problem, plus they would feel kind of "used".
