How big is the risk of using "Sinatra Beats" as the name of my channel?

I've been loading and selling hip hop / cheat instruments on YouTube for a couple of months, but I'm worried that they will sue me for using "Sinatra Beats" as my name. My real name is Sina, so I think I should justify a little more use. I'm still quite small, so it's not a problem at the moment, but I'm thinking about the future of my business and the possible complications.
