YT banned my video!

YT uses technology from Audible Magic to detect copyrighted audio content. Whether you have the title of the song or name of the band in your description or video title has nothing to do with whether youtube detects it or not.

Basically, how they do it is they use a very loose hashing algorithm (also known as perceptual hashing) to compare your song to a large database of known works (samples submitted by the music industry, it is an opt-in thing on their part). The actual nitty gritty details are fairly boring unless you like math, but if you are interested you can read up about it, just look on google scholar or something for perceptual hashing algorithm implementations.

Depending on what kind of algorithm they are using, it may be possible to bypass the detection using a combination of methods, though I have not tried this experimentally. (Don't have time, and don't feel like getting a few youtube accounts banned and risking my others.)
* Some algorithms factor in the fundamental frequencies of the musical notes, which can be circumvented by pitch-shifting or speeding up/slowing down parts of the song.
* Also, it may possible to phase-invert the music, or parts of the music. This produces very different data and has the potential to (though it won't get by the Fourier transforms used to calculate fundamental frequencies) The nice thing about this is that it doesn't affect what is heard very much.
* Adding spectrum-wide noise will absolutely throw off the filters. Essentially, you want to degrade the music quality so much that it is recognizable by a human ear, but not by a computer program.

If someone has a lot of time to burn they can try these methods. I don't think putting bumper music in will help, because I have a suspicion youtube tries to match short chunks of music at a time.

I wonder if the Audible Magic technology would remove Coldplay's "Viva La Vida" if Joe Satriani's "If I Could Fly" was flagged for removal...

musicians have stolen from each other for centuries. the beatles took all kinds of other tunes and stuck them randomly into their own music. they didn't even try to hide it. the great igor stravinsky once said, “good composers borrow, great composers steal.”

copyright law fucks everything up.

I had this problem not so long ago, I re-uploaded the video without any tags relating to the audio, its still there now.

It's happened to me for my Sekirei AMV, YT blocked it because WB owns the rights to the song I used (Take Me or Leave Me from the RENT soundtrack)

and of course I've had videos reported by douches, that were then blocked.

YT has a very half-assed/hypocritical stance on the copyright issue if you ask me, they'll block any new content that they see as infringing, but won't get rid of stuff that has been on for years that uses the same song that the blocked video has.
