Good: Media Controls on my lock screen, media controls on my phone's lock screen through KDE Connect, plays my music, adding stuff to playlists is super easy.
Bad: Some stuff is super small on my screen. After finding the tiny player controls I still can't visually tell which is the play button (HiDPI)
Ugly: Smart playlist->all tracks creates a playlist with all tracks in apparently random order. Too smart for me.
Meh: Lots of features that I personally have no interest in using.
