Recommend store friendly songs for demo purposes

[lonesome killer]

We demo sound systems (mostly Bose) at the store and I would like to demo a variety of genres. Problem is I only know country. Please recommend some store friendly songs (no cursing, etc...) from a variety of genres. Preferably something that can showcase why you need a sound system.

A few vague genres i guess. Not sure about all the words to freya but shouldn't be anything. Speaking of sound systems dear lord do i need something new.
