OK to post crowdsourced jobs on resume?

[jwdesign336]

Hi forum. I'm a new designer, and I know the dangers of crowdsorucing. primarily I am using it as a means to build up my portfolio. I was wondering if it's a good idea to list them?

Say even if I didn't win a contest, would it still be OK to put it on my resume?

I think the work I'm doing is sound design, and generally, I can tell that my work is more solid than half the other designs I see on sites like crowdspring. There concepts are so generic, however, the greatest majority of time, a client will pick the most generic flashy design.
