I've always been a huge Knopfler fan and Telegraph Road is one of my favourite pieces of music (live version's best).
Actually I prefer the outro on the album version. I really like the way the focus shifts between the various instruments, rather than just being focused on the guitar. The live version of Sultans of Swing is very nice though.
The solo in the Red Hot Chili Pepper's Can't Stop may only be 7 notes long but it is very good indeed.
Others I really like include Hysteria by Muse, Long Snake Moan by PJ Harvey, Someday I Will Treat You Good by Sparklehorse and Lakini's Juice by Live.
