Well, I'm really sorry for the people here at the audio portal crying foul over their work being misused (by "misused" I mean anything from no credit to original artists (and lets face it, SoundCloud really seems to fail at actually having a place for the uploader to describe an overview of the work, outside of commenting on segments of the song.). Fame has its price, and sometimes it will be in a very bad way.
Now before any vict-- er musicians get all "Phantom of the Opera" here, I just wanted to make note of a few things:
<|> The NewGrounds Audio Portal is powered by the Creative Commons-NC-SA License, and this is one thing above all else should be made of mention to the artist (or charlatan, if you prefer) if you are one of the persons who got their music "thefted". Cetacea should make note of referring to the majority (if not, all) of the uploads as strictly cover music, not being able to make any [commercial] albums with them until she first and foremost attributes/contacts the original artist for permission which is technically built-in to any music related CC license. She's technically on a threshold of trouble, and would be disastrous if (1) the uploads get a copyright (C) license and (2) the "covers" get her royalties, without the original artists permission.
<|> One person going by the moniker of "2DPolygon" has made it a mission already to nag Cetacea into rethinking her actions, by essentially bombing what looks like the entire songlist with a stolen music notice. I, personally see this as a double edged sword; For one this one voice is making a fuss, and its likely to get her attention; for the other, this may cause some unwanted reactions to "2DPolygon" as well as Cetacea, for as far as I know, the integrity of her fanbase could be strong enough to deny such a claim, or even going as far as to refer to "2DPolygon" as a spammer (which is technically what the fellow from the Netherlands is doing, even if for a good cause). Please just send her private messages, and I'm sure that way that if she gets enough of those, she'll more likely make amends to see to it that there are adjustments made that will please both the original NG artists and her loyal listeners/followers.
As for me, I guess I'm happy that my works (that includes the covers as well) are so rank, that she or any other audio thieves in the world would most likely feel shamed to take them as it could risk destroying their image. Anyway, I pray that this all can be resolved in a civil manner, where no one has to be murdered or become a prison be-yotch for a considerable amount of time.
xKore (the OP), there's hope that this will be resolved, and I think that since your Magnum is currently sitting atop this week's top 30 (that's some serious personal acclaim if you ask me), I wouldn't suggest sawing off the chandelier chain just yet. You do have every right to be mad, but I'd just send a message of concern covering some of the things I mentioned earlier, and hopefully you'll hear a reply soon. Attorneys/authoritahs should not be dragged into this until such time as she decides to publicly announce an album that 100% violates the CC license.
Again I'm sorry to hear this is happening, but its something we music people will have to deal with until the end of time.
