i've noticed that once i find a particular chord sequence that sounds so nice in the context of a song, that part excites me and i play it repeatedly. and once i notice the same sequence in other songs, i play those parts repeatedly too. but after a while, once i've gotten so familiar with that sequence, it doesn't excite me nearly as much. one of the examples i can think of is when i first noticed the i-VI7 progression in a song and it sounded great. it still sounds great in the context of that song but is not as powerful. do you think i'll ever feel the same way again about musical things that once excited me
maybe not but there's infinite more things to be excited about
