los campesinos! will have finally been toppled off the top of mine when it gets updated next:

1 Slint – Washer 32
1 Los Campesinos! – You! Me! Dancing! 32
3 My Latest Novel – Sister Sneaker Sister Soul 31
3 Los Campesinos! – It Started With A Mixx 31
5 King Creosote – Marguerita Red 29
6 Disco Ensemble – We Might Fall Apart 28
7 Shutter – Sedona 27
8 Art Brut – My Little Brother 26
8 Shutter – Crystal 26
8 My Latest Novel – Pretty in Panic 26
8 Wolf Parade – Shine a Light 26

LC! & Shutter both rank highly as they don't have that many tracks and I listen to them a lot while that Disco Ensemble track always comes up in my recommended radio, the others are fantastic songs.
