> Even using a 6|8 would be interesting.

There is a decent amount of pop music in 6/8. I always joke that it's like a hack to making a song better because 6/8 is rare enough that it makes the song sound interesting but common enough to not alienate the listener. It ends up sounding mostly like a hard swung 4/4 but then fills and some melodic lines are just a little bit more rhythmically spicy.

Some examples:

* The Doors - People are Strange

* T. Rex - Hot Love

* Fleetwood Mac - Don't Stop

* Depeche Mode - Personal Jesus

* Marilyn Manson - The Beautiful People

* Green Day - Longview

* Oasis - Lyla

* Blur - Parklife

* Living Things - Bom Bom Bom

* Britney Spears - Womanizer

* Goldfrapp - Strict Machine

* Feist - My Moon My Man

* Gotye - Heart's a Mess

* The Black Keys - Gold on the Ceiling

* Paul Kalkbrenner - The Grouch
