Ambivalence Avenue is a truly stellar album, so it's kind of painful to see it chopped to bits like that.
After listening a couple times, I'm pretty sure they're not actually the same set of notes. And even if they were, it's more likely coincidence than not: the musical effect Glass is going for relies on a particular progression which just happens to partially overlap a phrase Mahler once used.
Meanwhile, if you want soundtracks which shamelessly quote classical music...
* That awesome sequence in "The Matrix" where Neo's distracted by the woman in the red dress? The soundtrack gives you Rob D's "Clubbed to Death", but that's just the theme from Elgar's "Enigma" variations with a bass line.
* Listen to the score from "Gladiator". Then listen to "Mars" from Holst's "The Planets". In fact, this works with almost any action/war movie.
* Disney does it too: "Once Upon a Dream" from "Sleeping Beauty" is... well, a melody from "Sleeping Beauty" the ballet, by Tchaikovsky.
* A 1950's musical produced a hit song, "Stranger in Paradise". It's a melody from Alexander Borodin's opera "Prince Igor".
etc., etc.
PS: Somewhat implied but IANAL.
You really only need to be concerned about whether you're violating the law of the country you're in. AFAIK, you'd only be committing secondary infringement in Canada if you sell/rent/redistribute the song.
I don't think using a proxy in this context would be a violation of copyright law and I wouldn't call it a clear-cut question, so you should really cite more than "copyright law" as an answer to sant0sk1's question.
Also getting something is not distributing, it's causing something to distribute.
If you manage to avoid getting into contract by side-stepping "I agree" button, you are obtaining content without a license, hence violating copyright law. The act of side-stepping can be construed to mean "unauthorized computer system access", aka "hacking" or "cracking".
None of this is likely to get you prosecuted, but then if prosecution is all you care about you could use other means to obtain content which are also not very likely to get you in trouble.
This is not a legal advice, I am not a lawyer.
