Old Lyrics 

Hello everyone, i would appreciate your help on this very much, i'm trying to open a Lo-Fi youtube chanel but i don't know how to start, i already have the design etc... But when it comes to the "copyright" thing i get lost...

How can i use music from other artists and have permission of their music?

Asking them via e-mail? And in that case, we'll need to sign any contrac or something?

Can i monetize by promoting their work?

Thanks guys
