You aren't a source so you telling someone "I can sell. But you need to vault them." is the equivalent of saying "I bought these. Was told to vault. I need money because I can't afford these flop songs really. So you need to vault them or I'll get in trouble". But that's just my 2 cents.
I don't know either of you. however, the cmiley user uploaded screenshots of you agreeing to the deal. here's you, days ago, claiming that it was "going to leak". so you knew, no matter what, that the song was passed before you agreed to the deal. you're in the wrong.
