Post music that you use to focus while doing work, or what have you. One of my personal favorites is the Infinifactory soundtrack to just have on in the background. Here's a link. https://zachtronics.bandcamp.com/album/infinifactory-ost
...dunno if this counts as music per se but I usually listen to rainfall noise when I work? it's a very soothing sound, it blocks out other sound really well, and it doesn't have distracting lyrics or particularly cool instrumental bits or anything like that. there are online generators as well as like 10-hour videos of just rain noise on YouTube.
Skyrim sound track, every time. I remember reading an article that said video game music was designed to keep you focused on the game and would help keep that going with other things as well, so I've tried it every time I want to sit down and cram out some writing and it's worked like a charm.
I have a couple albums where I know every note due to repeated listenings. When I need to Get.Shit.Done. I put on one of those. It's not so much the style of the musice (although they betray my age), but the fact that I know them so well that I feel comfortable with them as a background.
I mostly just listen to classical music playlists on 8tracks. Here are some good ones! http://8tracks.com/tadashis/constellations http://8tracks.com/outstretched/ravenclaws-an-instrumental-mix http://8tracks.com/caaroe/thoracolumbar-fascia-the-study-playlist
