“Hello Friend, We just released this song please LIKE and SHARE http://stupidsong.com/”

If you do this – you suck.

“Man i’ve grinded so hard. I copy pasted to 6000 people. But somehow facebook has cut me down and someone reported me what the fuck”

Why is that? Your message has no fucking value. It’s annoying advertising.
Take time. Talk individually to individual people. Your ex class-mate from 8th grade does not give a fuck about your song. So don’t message him.

Read this book: How To Win Friends And Influence People – Before you direct message another person about your purpose. Make your interaction awesome.

Think about who you are messaging your shit. Make it valuable. Make it something cool for them.
If your music is fucking awesome you maybe don’t even need to direct message. You just post it and people share it. It needs to be really great tho’. People actually use the share button. But it needs to be great.

Thank you for reading and maybe eventually watching 🙂
