I went to the library today and thought „why not recording the noises of books and hard-working people?“ no music, only background noises :) there are several parts to it, so you can take a break after each sequence
went on and finished a whole subchapter of the thesis. I hope, this can also help you with your focus!
my first episode, with background noises etc., feel free to leave (constructive) feedback :) i listened to the playlists “instrumental study music” (xi chin) and “romanticising late night studying” (easy study music chillout)
