I do karaoke every friday night. I like doing lead vocals. You?
I haven't done karaoke in quite a long time, I don't know if I enjoy it or if I just do it to face my social anxiety. 
I like sing -alongs that use new technology. It's better f you sing with multiple people!
What type of new technology are you talking about?
Well in the late 1960s and 70s , the portability of band and instrumental music materials was revolutionized.
