At first it did seem like spamming, but I am at peace with it now. It is analogous to the FB Like button. You should only tweet out stuff that you like, and want to share and download.

I just got a Dell Vostro 3400, and am quite impressed. Clean design, multitouch trackpad, nice battery. Just missing the MagSafe power. It's the first PC laptop I could imagine myself using every day, if I couldn't use a MacBook.

We expect anyone who makes music to upload. We have a few famous artists like The Streets (http://bln.kr/-skinnermike), some internet famous folks like Levar Thomas (http://bln.kr/-LeVarThomas), and plenty of people just trying to make it. We also have hobbyists who just want to share music with friends.
