ye. making HEAPS of music + sitting on it gives good perspective for what's good and what's shit. (or, in afx case, what's good and what's amazing).
the soundcloud really shifted my perception on the dudes music.
the released albums are all so perfect and finely put together and it really gave this guy the aura of being some music god.
the soundcloud kind of shifted that and removed the god status. now he just seems like a guy who's super into making music as much as possible (and happens to make really, really, really, really, really good stuff).
so yes. i don't see the point in bringing up the new/old tracks point all the time. sitting on old tracks just means when they are finally released they'll be released in a good and proper context (much prefer something i can put on and listen to as opposed to a mish mash of songs).
+1 shows that he's got where he has because of hard work, love for music and not just great talent.
