Good thread. There's not much crossover between what influenced me when I played drums in high school and what went on to influence me in my fairly unambitious songwriting. Drums wise, it was down to solid classics - Led Zeppelin II, Nevermind and, ahem, Rust in Peace by Megadeth. Songwriting wise, I think Songs From Northern Britain by Teenage Fanclub was crucial - the vocal harmonies and sweet guitar melodies really got me. I also revisited Pet Sounds from a perspective outside of just singing Good Vibrations in the car. Lastly, Silver Jews' Bright Flight was the last album that really blew my mind from the position of my own songwriting. Seriously well crafted lyrics.
