I'd do some pretty well known stuff that stretches over all genres, and then maybe do some more obscure stuff like songs off of albums that got overshadowed thanks to popular songs.
As far as popular music goes, you can never go wrong with
Ke$ha - Your Love Is My Drug
Rihanna-Rude Boy
Shinedown - Sound of Madness
Black Eyed Peas - Imma Be
Nicki Minaj - Massive Attack
Lady Antebellum - Need You Now
B.O.B. - Nothin' On You
Muse - Uprising
Jason DeRulo - In My Head
Train - Hey Soul Sister
For some well known rock songs I'd play
Doobie Brothers - China Grove
Dio - Holy Diver
James Gang - Funk #49 or Walk Away
Def Leppard - Pour Some Sugar On Me
KISS - Detroit Rock City or Rock and Roll All Nite
Guns N' Roses - Welcome To The Jungle
Motley Crue - Dr. Feelgood
Dio - Rainbow In The Dark
ZZ Top - La Grange
The Beatles - Come Together
Metallica - Enter Sandman
AC/DC - Thunderstruck
Alice Cooper - School's Out (this would be a particularly good song to play if school is ready to get out over there like it is over here in the states)
Winger - Seventeen
For some obscure or less popular rock songs these would be go
ZZ Top - Waitin' For The Bus
Alice Cooper - Brutal Planet and Dirty Diamonds
Guns N' Roses - Think About You
KISS - Jungle
Breaking Benjamin - Shallow Bay
Boston - Amanda
Winger - Down Incognito
Dream Theatre - Panic Attack (a little long, 6 minutes I believe but it is a really good song)
Motorhead - Love Me Like A Reptile
Queen - Killer Queen (hardly obscure, but less talked about than their other songs)
Dio - Stand Up And Shout
Heaven and Hell - Bible Black (pretty much Dio era Black Sabbath all over again, great band)
Rainbow - Death Alley Driver
Van Halen - Spanish Fly
Motley Crue - Afraid
Ted Nugent - Fred Bear (amazing song)
KISS - Within
Also Slash just released a solo disk that has some killer songs on it, particularly
Dr. Alibi featuring Lemmy
Beautiful Dangerous featuring Fergie
That's all I got, hopefully I was of some help
