Youtube recognizing songs

[vsub]

Am I doing something wrong
No matter what song I make youtube recognize(search with your voice feature),I always get "Didn't hear that. Try again."
I am playing songs FROM youtube with millions of views and that feature still shows the same thing but when I try this site "www.aha-music.com",it's rare not not recognize the song

The steps are the same
1.I click on a button to start recognizing
2.A popup appear asking me if I want to allow the operation and I click on accept(is it set to record from Stereo Mix and I can see how the icon is moving according to the song beat so youtube actually "hears that"...don't lie)

Moving to MozillaZine Tech as this doesn't seem to be a Firefox issue.
