No, assuming filters are easy and foolproof is intentionally stupid and ignorant. Google took years to develop the technology and it was because they had the massive capital at their disposal. But all it takes to get around the technology is apply a few audio/video filters to get around the fingerprinting technology and words and phrases don't work, what if its a celebrity gossip video on Rihanna? That's fair use. The technology Google developed is easily gotten around by those determined and hits enough false positives that people with legitimate content have their videos taken down for no reason.
As far as the suffering of the music industry. Music sales are up, not down. There are also plenty of studies that show people who listen to artists online for free have a higher likelihood of purchasing the album online or attending a concert. People are buying more indy artists, not just what they hear on the radio and the middlemen in the record companies no longer control the distribution channels or who is exposed to what artists. Artists are benefiting from this loss of control, so I don't exactly feel bad for Universal, a one of the many record companies that has fought tooth and nail against any progress in consumer friendly methods of distribution and a legit and easy alternative to pirating. It took Apple to get them to finally let people buy audio files, and even then it was locked down which hurt people buying the music, not the people downloading MP3's off Limewire. They created the situation they are in now.
They don't need to filter the audio files themselves, that's completely un-needed, all they need to do is filter the meta data (eg: artist name, song title, album name). That is not hard. If you have a list of artists with their songs and albums you could easily match the submitted data against this and work out if the submission is disallowed. If they upload with "fake" meta data (eg: fake artist name) it doesn't matter because no user is going to find that music.
