I've been lookin' thru the posts to see what you're singin', and I haven't seen much about Country/Western or Folk Music. Is it all Rock and Pop?I think there's a lot of pickin' too.
I personally play/sing tunes by Bob Dylan, Arlo Guthrie, Fred Neil, Leonard Cohen, Chad Mitchell Trio, Kingston Trio, Donovan, Dave Van Ronk... lots of old folkie stuff in my repertoire. But then I grew up listening to them when they were new. I play a lot of tunes that were staples in the folk circuit back in the 60s.
I also play Beatles, Byrds, Rolling Stones, and other classic rock. Tunes I played in bands and jams in the 60s and 70s.
I play old R&B and MoTown tunes (not the modern pablum mis-represented as R&B today: I mean Aretha, Otis, Wilson and the greats).
A bit of cowboy music (the old stuff, mostly pre-1950; the kind Ian Tyson often plays - not the new country which is so formulaic it gives me hives).
Blues: I don't play as much blues on the acoustic uke as I played on the electric guitar, but still play some.
Plus I play a lot of songs from the 20s and 30s; tunes my own parents would have known. Love that stuff. Great music that is sadly often forgotten today. And a few of the standards from the 40s and 50s are in that list, too.
New pop? Almost none. There's some good music out there, and good musicians, but there's a lot of derivative pap, too. Way too much.
For me, pop music reached its apogee in 1970 (call me an old fart if you must, but I still hear the old Beatles' and Rolling Stones' tunes on the radio, 40 to 50 years later). I play mostly what I grew up with.
Finger pick: yes: folkie style, my techniques on the uke developed from almost 50 years on the guitar, mostly acoustic.
Depends on the song, but my own technique is a combination strum/pick. Use all of my fingers and hand.
Some songs I simply strum. Depends on the song. Depends whether I'm singing, how well I know it and if I feel it needs some fiddly finger bits.
