For some reason I really enjoy playing Gimme All Your Lovin' (the mighty ZZ Top), despite most of it being 8th note Cs!!
The other current fave is Ruby (Kaiser Chiefs), again nothing hard going on but I love playing it
Oh, and I Kissed a Girl, coz of the phat synth
EDIT; so, those three are all fairly well known. The band doesn't have one we do for our own pleasure as it were, but we do stick little things in a lot of songs which make us all turn and smile
