A few years ago when I was below the age of 15 I uploaded a Tiktok with mostly talking but a little bit of music which I didn't realize was a sin. The video ending up getting 5,000,000+ views and I was overwhelmed at that time with happiness. Now that I look at it, won't the over 5 million people who heard the music because of me get me sin? I was below age 15 as a male so I'm not sure. I'm trying to log in to the account and get rid of it but what if I don't succeed?

1- Try to delete it
2- Ask Allah to remove its effect
3- Do good deeds (like making a good clip) and ask Allah to expiate the effects of that clip. Allah is merciful.
4- Pray Allah guides and forgives all those who watched it
