came here to post this.
I picked up playing harmonica last year. I can play a few songs by hard but getting good takes practice. Some of my favourites are:
The Shire (from LOTR), sounds awesome, the refrain/start is easy to play!
Auld Lang Syne, easy to play, sounds nice
Beethovens Ode to Joy. first song i have learned, still one of my favourites because its fucking easy to play haha.
