If there's one thing I learnt from some of these bands, it's that certain partso f the song dun always have to go to V before it resolves to I. Example, Some chorus may go, I, vi, IV, then go I vi IV, then IV V I/vi . It lends the song some tension at some point and creates some surprisingly refreshing melodies becos of the jump from IV straight back to I. If you get what I am talking about.
ELT (Jap) also has some great songwriting.
