I've been using hacks for quite a time, more recently PM, and I've noticed that the songs that play on the stages is not really following the My Music configuration. Usually, when I turn on the game, the first time I select a stage, ALWAYS the same music plays on it, on the next select the music cycles normally. Is it a glitch or something?
There are maybe 2 options for this:
1 - You didn't correctly set up your songs in My Music.
2 - You have the same songs on the hacked musics.
We could add maybe add a third option, which would be PM messing with the songs because of the codes. But I highly doubt about that one.
