Here's my picks.

This House Is Not For Sale
The obvious choice. A great song, great chorus, great opener and the outro with the extended solo really sets the pace for the concert.
Probably the strongest opener from a post-2000 album second to One Wild Night and tied with Bounce.

Knockout
Not in my top 3 best songs from THINFS but it fits well together with THINFS. The drum intro gives a nice vibe for a stadium and the chorus is one of the most obvious arena anthems on the album.

Roller Coaster
Probably my favorite of THINFS. One of those great songs to put in early in a set. Uptempo, short and head-on. Also seems to go over quite well with the the audiences despite not being a hit (even though Jon loves to believe so).
