This isn't really technique so much as theory, I'd say, but anyway, it might fit in here as it is more related to playing and listening (as opposed to products). Anyway...
I've started encountering 6/8 time in surprising places. For example, I was teaching some kids the children's song "Pat-a Cake, Pat-a-Cake, Baker's Man" this afternoon [from a children's song book] and saw it was in 6/8 time!
When I got home, I made this little list that hopefully other people (that means you ) can add to:
Songs in 6/8 Time
Old Friends – [Simon& Garfunkel]
We Are the Champions - [Queen]
Lights - [Journey]
(How Can You Mend) A Broken Heart - [Bee Gees, Al Green]
Norwegian Wood (This Bird Has Flown) – [The Beatles]
Row, Row, Row Your Boat
Hickory ****ory Dock
This Is The Way We (Wash Our Face)
[aka “The Wheels On The Bus”]
I'm not "100% beyond the shadow of any possible doubt" positive on all of these, but I've either seen them notated as 6/8 or they count out as 6/8 to me. Also, I realise that there can be more than one way of notating the same piece, but I'm not really looking to get into esoteric arguments or anything. Basically, all I know is 4/4, a bit of 3/4, a bit of 6/8, some hazy memories 2/4 from way back when I was in elementary school band(!), and some experiments on my own with 5/4.
Anyway, 6/8 has kind of caught my attention lately, as I play almost entirely in 4/4, but I'm seeing that 6/8 is more useful and more widespread than I had imagined.
Please comment on your experiences with 6/8, as well as add any popular songs (even kid's songs) to my list. Also, if you feel I improperly included a song, you might mention that (and why).
[edit: I removed '59th Street Bridge Song' and 'Crazy Little Thing Called Love'. After reading comments below, I re-listened and counted and have decided I was previously insane when I figured them as 6/8. Also, I added some more children's songs]
