The thing my dad has done with technology that has most surprised me is him figuring out how to use Spotify to expand his musical horizons. He's always played the piano and guitar but I never really saw him listening to music very often as a kid. Even in the car he will pretty much just put either the classic rock or the alternative rock station. Then he got Spotify. Now he's in his 60s and discovering new music on a daily basis, getting into all sorts of genres hes never listening to, and making playlists of stuff he finds interesting. This has resulted in him diving into the history of a lot of this new (to him) music and that has been awesome to talk to him about. Most people stop really looking for new music in their 30s, so for him to be in his 60s and blossoming his musical taste so much is really rad.
