Hello, I believe that singing to a group or a singer you like will help your voice, I would never have thought I could even come close to singing in a Operatic style if it weren't for this band Nightwish I listen to all the time. However, I also felt like I was trying to copy her voice to much to where I was forcing my voice to go lower than it can really go. But now that I am taking voice lessons I'm starting to realize my voice is much higher(Which I never would have thought, because it sounds so hard)and I can sing to Nightwish but at my own range. But singing to singers you like I think that really does help, when you enjoy singing to something you love I think that helps you learn better.
