Hi! I've been working on a slightly goofy heisting/sneaking type of game and I'm now making a small loop that will play in the background. I was wondering if there are any guidelines or something to keep in mind when making tracks like that, especially as they're there mostly to set the mood while allowing the players to talk with eachother without the music being in the way. I get that the music should probably loop nicely, but how long should I try to make it? Should it have different sections that are indistinguishable from eachother or should I stick to a simple rhythm and melody? Are there some frequency-bands that I should not fill or something? I'm still a complete noob at all of this so I'm sorry if this is a stupid question. Cheers!

Here is a track I composed inspired by "From Past to Present" from Skyrim! Let me know what you think!
