I just had the exact same thing happen to me.  IODA claimed ownership of a piece of original music that I wrote myself in Garageband.  I trusted in YouTube's appeal process so I disputed the claim and said that I wrote it myself and the dispute was promptly rejected.

Now my video is not monetized and I have links to buy this completely unrelated music plastered all over the description on my video.  This is blatant fraudulent misrepresentation by IODA.  They need to be shut down.  How dare they claim to own something that I created and actually profit from my own hard work to boot?
