Lately I have been learning (and now playing) some fine music from the British Isles. In the folk music genre, on the mandolin and violin/fiddle, I've recently learned Rights of Man , Off to California, and Sailor's Hornpipe.
On the classic rock side, I just acquired >> If I Fell, In My Life, and I'll Follow the Sun, by the Beatles, and Old Man, (American) by Neil Young. Love the chords on these songs.
Those are fun. My personal favourite subgenre is the Scottish reels of Cape Breton. I'll post some when I get more time.
Meanwhile as a random choice check out this medley. She's from Donegal. Actually not totally random, as it starts slowly with a Strathspey and builds up gradually to a fever pitch which is typical of Cape Breton.
