Sing for Needs - music charity logo

I'm creating a branding for a charity called Sing for Needs. It's a platform which provides space for artists (singers, DJs and other musicians) to connect with charities through causes and then performances. Imagine it as, when someone is running a marathon for a cause.

I'm in-between of some directions so I kindly ask your help to give feedback only on the logo, which is more focusing now the symbol than the combined mark altogether. Thank you! ??
