Jimmy91 simply seems to have a confession, and it's Doom music, or at least music for Doom he is writing. For about two months now you can follow him on his livestream from time to time in his own channel, and even check some of the sessions which already have been passed since then. So if you are curious or just want to see how creative and musical people get their tunes done right, you should stay tuned and look for any upcoming livestream Jimmy has planned so far - it's worth your time and very entertaining. More info can also be found on the Doomworld thread.
