For me this is the best piece of music in 7/4 since Money - It's a song called 'Bubbles' by the Scottish band Biffy Clyro. http://www.youtube.com/watch?v=wIY1ZSZvAaM
The 7/4 section starts at about 3:25 and lasts the rest of the song. I just think its great because it's catchy, and took me a while to realise it was in an odd feel.
Any thoughts? Or any other contenders?
