What's the best music to study to when you need to read and remember lots of info?
How can anyone else even answer this question for you? People will study to any music they want generally. There obviously isn't any music that is going to make you magically smarter.
But fine, here are some things I listen to while studying or just reading for pleasure:
Bach pieces for solo keyboard
The last two talk talk albums
Selected Ambient works II
Brian eno Ambent Stuff
Just fucking thunderstorm recordings
