When I was jailbroken previously and bought Auxo it crashed with Spotify. Since its last update there has been no issues. Hack repos are often behind with the latest version, hence why most people with issues either a) pirated and have an older version or b) another tweak or theme is interfering with Auxo.
I hear you on the pirated copies.
But I have also purchased many bad and buggy cydia packages before and they still crashed even when paid.
I remember yourtube, that thing was a piece of junk and the author instead of fixing it he was putting out new and more crappy packages on cydia for sale.
