CuteSpotify has been renamed to CuteSpot:
Thus you will lose all your offline music, and have to reload everything.

It is recommended that you uninstall the old application and delete the following directory: "/home/nemo/.local/share/harbour-cutespotify" to free the previously used space

Furthermore, I think I finally fixed the startup crash, this time for real.

You find the new version on OpenRepos:
