To be honest i don't know about this one. When you change the tune of the first few notes it sorta...well. trying not to be rude here, you should probably add much much more bass to it and try not to be soft. when it comes to the tetris theme it doesn't matter if it's to loud.
heres a tip. next time you make a Tetris theme remix think whether or not people will dance to your song and how they will react to it.
