I went down on a rabbit hole of stolen audio.
Stolen from Imagine Dragons "Bad "Liar":
Author Comments: "Imagine Dragons gave me permission to use this song, because trust me" and "NOTE: This song will be used for an upcoming GD Insane Demon Megacollab"
yeah I don't think "trust me" is gonna cut it. Uploaded a song that he didn't own to use in Geometry Dash.
