BlackSheep and IceFire made TBP music tracks from the ones that were released to public by Franke. Originals were low-quality (128 kbps) but it does fine in FS2.
musicofb5.com is long gone but you could download the tracks from somewhere else, forgot what was the site's name. Also extended ITF soundtracks were made available by Darkblade and me, but if you want those, you're quite late unless you find someone kind enough to host them for you.
Of course, I have ftp running almost 24/7 but I am not going to host the tracks. These were available by me as a torrent download, but I took if offline due to lack of seeders long time ago.
Thread about ITF extended tracks. However, you will not be listening to those tracks in TBP because it would be calling for possible trouble. Things will however change if we get a permission to use those tracks publicly in non-profit manner. Unfortunately even after months and months of trying, we didn't get an answer.
Before you go and post about how about trying this and that. Forget it, we already tried. Go read the thread at FO.com.
