Some people have opinions on music. I'm one of them:

Hey everyone, this is my new cover on youtube and I'm fairly new to this and I'd love to get some feedback and comments ! Thank you all very much, I really appreciate it !

A while back I started to add a short (2-3 second) intro to my videos, but someone pointed out to me that I shouldn't do that. Now I have started to doubt myself, what do you guys think? (the video in my signature does not have that intro).
