If you're looking for a more feature-rich music player with streaming service integration, you might want to consider other options like MusicBee, Foobar2000, or Clementine.
If you're looking for a free music player, the standard version of Droptop should be sufficient for most users.
I couldn't find any information on a "supporter version" of the Droptop Music Player. It's possible that the developer offers a paid version with additional features or support, but I couldn't verify this.
