I thought I would at least give an example...
Here is a guy I have worked with. Great guy, great vocalist. A quick example of a demo tracking session.
Rough Demo Tracking If you notice, it has an astounding 2500 views! That's, two thousand five hundred. I could tell though, this guy and his bandmate had what it takes. I see this often enough...not that I can predict it by any means though! LOL I'm just saying that had something.
Here is a song they released around that same time...
19 You + Me The lyric video got 4.8 MILLION views!
Then they released an "actual video" which got an additional 3.6 MILLION views!
It sold 720,000 copies.
It charted to #7 on the billboard charts.
Shay also ended up with two co-writing opportunities with Rascal Flatts as a result. Not to mention some of the people he got to co-write with.
I see the inner workings of the industry every day. If you want to find a reason it can't be done, there are plenty. If you want to finds ways TO, as you are probably seeing, you can!
