yeah taking a track and running it thru a whole bunch of stuff and then recording the output has definately lost some quality along the way, as for the intro, i actually really dislike the intro to game over, which is why i thought of mixing the two tracks in the first place, and yeah your right about the levels, the output on both is the same, but i think its that tetris has alot of high end, and game over has heavier mids, so its pretty noticable to the ear when it switches. cheers man
