# FIFTH UPDATE (18/11)
OK, back to business. This update will tackle many small things and bits I've came across, as well as many questions made in this thread.
But first, I'd like to explain the issue encountered yesterday, when I realized that BGM sounds/music for winning a license-trophy (bronze, silver or gold) are being muted if you have Race BGM muted.
I presume it will not be an issue for 95% of future GT5 players, but all Legacy Players (respect ) and all other players that tend to race with Race BGM set to OFF (as everybody should, but hey - De gustibus non disputandum est ) will probably find it annoying. For solving of that problem you'll need an empty MP3 or VAW file (GT5 will only accept 48, 42 and 20.05 sample-rate files) uploaded to your PS3 music Library, in separate folder. Once uploaded, you go to GT5 Options/Sound menu and then choose User BGM (for Race BGM). You then choose the empty file and make it play random in loop and then set the Race BGM to 100. Voila! License-winning music is there and our favorite Japan Guitar-Rock tunes will play happily in the rhythm of spinning awarded Trophy
