Phones these days have so much internal storage that I haven't had to use an sd card, although my phone does have a slot for one. I prefer to use plex and plexamp for my music so I have the conveniences of streaming services with the ownership and classic music player feel of old school devices.

Having tried Youtube Music, Tidal and Amazon Music, I feel that the UIs of most streaming apps and even most music apps in general are not that great.
