I think many people confuse the concept of a 0 bomber to someone who just doesn't like your music.
The concept of the portal is simply this. Sometimes i'll go through the audio portal and hope to listen to decent music, but get annoyed with how much music is just terrible. I vote fairly to these people, but i suppose some people get so tired of the crap that is coming into the portal on both the audio and Flash, that they just 0 bomb them all, assuming it all sucks.
But once your music is out of the portal dude, if you get 0 bombed, its probably because the music isn't that great to that persons ears. Many times i'll see people complain about this (Soro), but in all seriousness man, you have no one to blame at that point. You seriously cant expect everyone to like your music.
When people complain it annoys me, because the fact is that this site is a crappy site for musicians. If you want to take music seriously, newgrounds is a horrible place. Even the forum is crap, just filled with 0 bombing QQ's like this one, and failed attempts to self promote. Every once in a while you have someone talk about something really worthwhile, but its quite pathetic how rare it is.
I mean seriously! How are you guys still on this site? Do you think Tom gives a shit about your music? Hell no, he puts us at the fucking bottom of the damn front page, barely put any effort into making the audio portal successful, put in a voting system which is completely bull shit, i just...the list goes on.
The message is this. If you want to be a real musician, dont bitch about the problems when you put your music on this site. Promote yourself, and make your own site, or go to another site that is more music friendly. This site is a load of bull shit that could care less about its members.
