In-game music
 

So...this is probably gonna be really specific to a couple of people, including me...but...

Is there a place I can post songs that I play in-game? Like, a song that's composed by either myself or someone else? It's hard to describe, so I'll stick an example here: http://www.youtube.com/watch?v=1KT5Qhd-bQc

Would that be considered Art/music/games, or would that just not be allowed at all?

I would put it in the Music Discussions [personally, but your choice to put it elsewhere]. At your first thread just describe what the thread is about

It all depends.

Do you want to discuss the song being performed? Music Discussion.

Is the purpose of this to demonstrate your creative skill? Art Discussion.

Do you want to talk about the game you're doing this in, beyond just this specific performance? Gamer Heaven.

Do you want to discuss the general concept of playing music in a game? That could go in either Music Discussion or Gamer Heaven with no problem.

There's enough overlap in these categories that you have some flexibility in topic after the thread is started regardless of WHERE you start it, so choose from the three based on what your intent is.

And if you want a thread where you show off/discuss music that you play/portray in Role Playing game that is being played here? Not in OOC thread, if there's one, but solely for music of that RP?

Uh... You'll need to ask that section's mod; if you ask me, such posts would go in the RP thread itself, but apparently the social norms for avatar site forum RP works totally differently than either my own RP experience or my own forum moderation experience, so I'm not going to make any judgments in the matter because I tend to be wrong.
