If you are doing this for a music video you need to make sure to do the comments perfectly, or the whole "viral impersonation" can fall apart and others in the music business will be able to tell it is all fake.
Along with views you will need likes, favorites, subscribers, and the comments must look super real meaning the spelling, grammar, punctuation, slang and likes to different comments must be perfect. Also if there is nobody responding to other comments (eg. @commenter1 responding to @commenter44 and back and forth, ect.) then it will be easy to tell that it is all rigged.
I work with some very large musicians and there are ways to figure out what is legit and what isn't. There is a lot more to viral marketing than giving a musician FB fans, YT views and Twitter followers, quite a bit of work goes in to making things look viral and create hype. This is why almost all of my jobs are $xx,xxx-$xxx,xxx for clients, it's not easy work.
