What is the criteria for being considered for a Premium profile?

So, I have read up about these premium accounts by invite only. I realize this is a 2plus year long beta test feature. My question is... what do the SC team /or moderators... ( whom ever it is that actually extends out the invite to premium partner accounts.) Look for when inviting and artists or label to the premium feature?

Example's:
-Must I have over a certain amount of followers to even hit the radar?
-Personal music preference from the people who invite?
-quality of production?
-who the artist is associated with / label or popularity?
-amount of traffic to the artist profile ( some artist have almost no followers but a huge following out side of SC and get a ton of traffic )

**basically, what can I do as an artist to work toward the same qualities that SC is seeking when they make invites to the premium accounts.**

I have been an active SC user since 2009. (I have paid for SC since 2010, religiously.. every year ) Truth be told. I find great value in investing to SC since it seems to be my main online presence for my music. I like many artists, I'm sure; would love to continue to grow and evolve both musically and with how i represent my self online, on Soundcloud.

The premium features are very appealing and I would love to work toward upgrading my account to that status... I feel I have finally reach a place in my craft of audio production where i am actually proud of some of the tracks im putting out. even though I only have around 2k followers after so many years of hard hard work - and i see people... young kids on SC for less than a few months with way more pull than i feel i will ever have... but non the less. would like to find out thats its not impossible and that maybe. some how im not far off hahah :)
