When I was in high school, I used to listen to a post-rock band called God is an Astronaut when I studied because it was so background-y. I can't speak for their newer music, but circa 2012 all their songs were at the same tempo, had the same basic melodies at the same volume with the same basic soft/loud dynamic shifts. it basically just worked as noise to fill that part of my brain that drifted off-topic whenever I was trying to focus on something boring.
I can't link you anything unfortunately, but here are albums I used to listen to:
All is Violent, All is Bright A Moment of Stillness God is an Astronaute Age of the Fifth Sun
>>4 Seconded. Post-rock is great for work. Can't go wrong, I think. Simlarly, I recommend This Will Destroy You. Languages is a good album. Better yet, check out Caspian. Their newest album is fantastic.
Thirded. Fairly non-descript but pleasant post-rock tends to be my go-to study music on the off chance I actually listen to music while studying.
Though I wouldn't lump Caspian's new record in with those groups' because it's too awesome and just distracts me instead. Just picked up a copy of it tonight actually. One of my 2015 faves.
Go on youtube and type in Le reve dreaming, click on the first video you see. It's a very relaxing song I listen to it whenever I am writing for school or for fun.
