Re: not liking the music game. at all. AT ALL...
If you're referring to the quest where you have to play a musical instrument to open a series of vault doors, just hit one of the mini-game music buttons to start and wait. When the game is over (no matter how badly you played, or even if you didn't bother trying) the door will open.
In PotFF, there is another such game. Unfortunately, this time it's an unavoidable part of the main quest and you can't simply choose to not participate. Even more unfortunately, you can't just wait this one out like the other one. The good news is there is a console command that will get you past it. Open the console and enter "twoworldscheats" followed by "quest.cq 6644". This will tell the game you've already successfully solved the music mini-game and allow you to continue past it. Be prepared for combat when you do that, because immediately after the cut-scene, the boss attacks.
