Anything by Floyd really especially the more Gilmour type stuff like Wish You Were Here, High Hopes etc.

Favorite songs are probably Shine On You Crazy Diamond (I-V), especially love the live version on The Delecate Sound Of Thunder Album,
Wish You Were Here, in my opinion the best song ever written. Keep Talking, amazing lyrics particularly the Stephen Hawking bit, and On The Turning Away.

Favourite album is without a doubt Wish You Were Here.
