I sometimes refer to Every Noise at Once when I'm looking for the right music as background when I want to focus. https://everynoise.com/

For me the music has to hit a balance between being engaiging enough but not too abrasive, sometimes lyrics can completely derail my focus but I focus better when I have something to listen to to drown out the sounds of conversations and people around me when I'm trying to read.

If I'm doing something that doesn't require too much focus, like cutting things for a collage or cleaning, I can listen to podcasts and songs with singing. But if I need to read, write, or think about what I'm doing I generally cannot have the sound of someone saying something I can understand, sometimes if it's not a language I understand it can be fine though.
