We don't have "agreements" with any label, instead we send out a bi-weekly displaying what's hot and our top 100. Sure, they can go on the website anytime they want but it's not a guarantee that they will. Most of them expressed that they are not going to sift through all the music and they rather get a breakdown on what's hot.
As for adding more labels, we are always to get more to our list.
Remember, don't count on these labels going through Playce and buying. I'm sure they had their avenues of buying or creating music in-house before being introduced to us. So don't just upload your music and expect instant sales, market your music regardless.
But at least now we have their attention.
