Pro quality
YES!! This song owns! I don't even know what people like dimrain are doing on the top 50 (yes, I understand its a different section of the portal, WHO CARES?) when you've got music like this going. I mean seriously the only person I can really compare it to in terms of quality would be some of the people from deviantart.com, and they're like the 1337est of the 1337.
The chord progression, for one, is awesome. The vocals are also awesome, although honestly I can't understand half of them :P (Yes, I am hearing "I'm burning up" ... but thats about all ^^;) but that really doesn't detract anything.
The instruments, mainly just the synth, give the piece its awesome trancey feel, and as soon as that thing picks up at the beginning you know its gonna be a pwnage song. I also love how this song goes through so many different phases. From a 'no worry in the world' type thing at the beggining to a sader sound in part two, its all awesome.
Anyways, I can see what you were talking about when you said everyone said this is your best piece. Honestly I'm thinking that it would be impossible to top this one, at best tie its ownageness or hit its level in a different genre. Im also so thankful that you decided to make this song so long (was that even a decision, or did it just happen?) meaning that I wont get bored of listening to it for days.
By the way! Those straight tens you see up there ^ are somewhere equivelent between a mcPerfectBurger and a mcGodlyBurger... I'm not much of an audio critic but I've only given out two of them, ever, including this one.
... Unless I forgot about doing it sometime, which I doubt. ^^
Anyways, to sum it up in one word: AWESOME!!
