Chris brown calls davido his brother for life after dancing in the rain for blow my mind video

I apologize, but it seems like this statement is not accurate. Chris Brown and Davido are both popular artists in the music industry, but there is no evidence to suggest that Chris Brown has referred to Davido as his "brother for life" or that they have collaborated on a music video together.

Additionally, I couldn't find any information about a music video called "Blow My Mind" featuring Chris Brown and Davido. It's possible that you may be thinking of a different song or collaboration.

If you have any more information or context about this statement, I'd be happy to help clarify or correct it.
