Last.fm, I guess. I use Libre.fm as well, but I don't quite get the same experience out of it.
Free and Open Source Software
If it's free and open source and it's also software, it can be discussed here. Subcommunity of Technology.

I haven't tried last.fm but I like ListenBrainz for that stuff.
Games, Discord and banking stuff
QuickBooks. F that software. Give me any double entry accounting software that you can use with multiple companies.
There are a bunch. There are fewer that are multiuser. Search alternativeto. Thing is people want more then double entry accounting. Electronic payment processing, reporting, payroll, AR, tax... Then how does it work with the professionals you hire.
Edit: For personal stuff, my wife and I use GNUCash. It does have small company features. I do not think it is concurrent though, but it can be used with an SQL backend though. We do not use the database mode so no experience with it.
makemkv also basically most of my music software
Spotify and games
chrome, the android os and platform and all the apps therein. I mainly use firefox, but some things only work in chrome.
Gmail and Google Photos for shared stuff.
Podcast Addict I really want to use AntennaPod, but I can't do without priority podcasts.
Also Feedly. Feeder (FOSS) is so close, but doesn't allow different sorts for different feeds.
Square Launcher on Android. Tried a whole bunch of other launchers but keep coming back to the windows tile interface. Scrollable vertically and horizontally puts so much within reach so quickly.
Obsidian. Plain text files with as many or as few plugins as you want. All versions of the app look and behave the same (other than mobile, but at least android is kinda close). Nothing stored in a database file, no manipulation of the text files themselves (looking at you, Joplin). I'm open to another option but so far, nothing is as elegant and platform agnostic as Obsidian.
