I am doing as much as my development on Linux as macOS these days. As music is an important part of my development environment, I need a good place and player to get it from. Spotify is nice as it is cross-platform, and makes it so I have my music and playlists on either environment. But, as the Spotify client comes on Linux, it's pretty unusable. It functions fine, but on a 4k display, the text is almost unreadable.
I did some digging and found this gem on the Spotify forums. Here's the TL;DR version:
Exec to read
Exec=spotify --force-device-scale-factor=1.5 %U
(or to whatever scale factor floats your boat.
2.0 works best for me)
