There are several "radio chatter" and "in-flight music" additions for the IL-2 series, going back several years. None of which require a mod of any sort, just follow the directions on the package you're interested in, or create your own ... I ran across one that was all modern heavy metal instead of period music.

Lots of possible additions in this one place, not to mention all the others out there if one had the desire to find them: http://www.mission4today.com/index.php? ... oads&c=586 (pay special attention to the "randomizer" utility)
