guitar homework was to write a pop-style song using a basic GCGD chord progression and FOR SOME REASON my brain is like, stuck on a D, F, G loop and it's screwing me over bc F isn't even in the G major scale so i keep going down weird note combo pathways

so it sounds 100% *NOT* like a g major pop song but i also can't think of anything else aaaaauuuuggghghhhhfghghghghg
