Yo, if you're not with the iStandard Producers movement, you need to get down. I was with PMP Worldwide paying $50 a month. My dude, that's $600 a year! And all I got was a few nibbles from some people that didn't even want to spend $50 on a non-exclusive lease.
I joined iStandard for $100 for the entire year and I get to submit to the same artists as PMP and then some. I can post as many songs as I like to my profile. And every month, they have producer showcases all over the country. I went to the one in NYC at Webster Hall a couple of months ago. BANANAS! Sha Money XL came through for the Behind the Rhymes interview. I'm like 5 feet from Money... Incredible. Dude was down to earth. I got to kick it with him a few as well. There was a group of other producers there to, judging the showcase, but yo... Incredible experience.
Definitely check'em out. http://www.istandardproducers.com/
