I'm sorry......
...but this has no taste to it. No true diversity in instraments nor in the volume of the music itself. (its loud but it needs crescendos and decrescendos) Its been porly done and the only reason why some one wqould probably vote 5 for this is because of the fact that its titled 'Tetris Rocks' and also for the fact that it has a cheap sound of a guitar. And thats all it is.... a guitar... why didn't you add some drums or other instraments?(refering back to diversity of instraments). Please dont take it the wrong way. Notes wise...you didn't mess up.
