How can I delete a Sequence that was posted before i got an account.

[Stellar_Nova]

I made a song call Twilight Waltz in another website called Beepbox and uploaded it here to test this one out. I accidentally uploaded it as a public sequence without knowing what i was doing. It's even a song that I posted the original version on YouTube as StellarStudios, but i cant find a way to delete the sequence from here. this is a bit worrying that something will happen to it. Any help given will be appreciated.

repost it on your account and delete it.

If you want the original to be deleted, just ask a moderator

No offense, but it probably wasn't any good that anyone would want to take it. Just most people's songs here are pretty trash.

You cannot save the song online privately, all songs are public if uploaded. If you saved it to an account, you can delete it
