Q:

Are questions about names of in game music on topic?

I recently saw that this question about a song that plays on GTA Online was closed as Off-topic, with Wrigglenite saying in the comments:

I'm voting to close this question as off-topic because it's about Christmas songs, not video games

If you ask me, this question is about video games (in this case Grand Theft Auto Online). The asker posted a YouTube link showing the song in question inside of the Doomsday Facility, showing that is actually present in the game.
I did a quick search and found the following questions:

What song is being played during the mission Uninvited (Act 2, Mission 9)? (closed as "Needs details or clarity", but reopened once more information was added)
What is the name of the Halo 3 theme song? (there was a video showing the song, now taken down)
What's the name of the song in mission 14? (there is a video showing the song)
What songs is Lucio playing? (there is a video showing the song)
What song is playing in Cassie's earbuds during her intro? (there is a video showing the song)

Is this type of question on topic? I don't see any reason why they would not.

A:

I think questions asking for names of in-game music should be on topic. 
Music is such a a big part of the videogaming world. For a lot of people, a good song or soundtrack can make or break the game experience. It's so popular in fact, game music has even ended up ranking on music charts. Some games have had their OST released (physically and digitally), others have included it as part of the installation of the main game files, and others offer it for purchase as 'DLC' on stores such as Steam (Octodad and FTL are two that spring to mind). 
So the popularity is there, how about that sort of in-depth gamer knowledge that we could help with? 

Some game music is listed with very generic naming (e.g. 'Track 1','Track 2')

You see this in a lot of older games' 'sound' options like Streets of Rage or Tony Hawk, but also in games like Pokemon X/Y - selecting battle music in multiplayer for example. The expertise would be knowing what each track is, and being able to identify it, or give a more common name for it. (e.g. 'Music 1' is 'Trainer Battle')

Some games feature tracks that are very melodically similar to one another

Portal 2's You are not part of the control group and Forwarding the Cause of Science both share a similar basic riff and play in the same sections of the game. As quite a large game with 3 volumes of OST, it is easy to mix them up if you're hazily remembering a track from playing the game and not intimately familiar with the soundtrack.

Some games feature tracks that were not included as part of their official OST. 

A gamer's expertise would be knowing how to find this or what the track is named (officially or unofficially). (As a personal anecdote: it took me digging through Starcraft 2's compiled files to find this track and its 'No Lead' version).

These sorts of questions require the sort of gaming expertise that we can and should provide. In a way they are similar to (good) Game Identification questions but they start with a good leg up: we aren't left second-guessing if a linked source is actually from a game or not. So yes, I think they should be on topic here.
