How could I replicate this?!

So let's just say I own a record label and I'm looking to promote the music via viral marketing.

Facebook would be the #1 method probably due to its volatility.

Here's what I mean...
Example video 1: Results... Example video 2: Results... What would be the easiest way to replicate this? I'm not looking to spend a huge amount, so what's the easiest way to get viral like that? Contact other page owners? Start my own page? How would I build up an audience of 50k+?

Edit: when I say results, I mean look at the view count.

Be creative. These are pretty basic ideas. They are just find videos related to music and putting different music over them. Try to find a source that is funny (***** or reddit comments) and use their style of humor to get an edge on the general public.

Flow of content
reddit > twitter > 9gag > instagram > facebook > 9gag again > facebook again
