I have a few in mind, but if I had to pick...
Probably "Summer Dreams" by Skream. I like to think to this song (it kinda just has the right vibe for it in all honesty) and the cover reminds me of how I'm usually in the background, as in not standing out to others, which is something I used to stress out about a lot.
Plus, it's just a good song tbh
