6. Pet Shop Boys - The Resurrectionist (B-Side to I'm With Stupid)
The rare case of a b-side that's actually better than the single it's attached to, The Resurrectionist is classic PSB, and god only knows why it wasn't on the album. Actually, of all of the artists on this countdown, these guys probably have the most distinguished list of 2006 b-sides.

5. Delays - Broken Pylons (B-Side to Hideaway)
A gorgeous compliment to Delays' second single from You See Colours, this gentle ballad lulls along until it hits an astoundingly beautiful chorus. If a track can sound like a beach at sunset, this'd be it.
