Yarp, my SC links in the sig below.--->
...Only the product of my expensive 'hobby',.... though had a few positive comments, especially the track LSD.

If you use Soundcloud my old friend Matty from the band Binary Finary has set up a site for producers.
http://www.cloudkillers.com
The idea is that you sign up, post your track/s to the site. You then have random SC tunes that you are asked to listen to and make a decent, constructive comment on (no: 'Phat mate' or 'Nice',
real constructive comments, good or bad, no spam).
The whole thing goes a lot deeper than this though; Producer networking, marketing, advice etc...I couldn't start to explain all in this post (Will leave that to Matt).
There's also a Facebook group for any questions etc which is manned constantly...

I've not used it (or made any tunes) that much recently as have been sorting out the studio with acoustic panels & bass traps though found it worked really well when I did.
