Thanks for your review.

You were absolutely right. - I know the intro is lame.
The piano is the default but because I think it sounds the best.

You don't have to listen the loop version because this song contains the whole loop section without any changes.

About the name... I call it double major because in the loop (which is the main theme in this song too) the whole song starts with two minor chords and than I put it upper with a semitone and repeat it so there are many many repeated minor chords. So in fact this name is absolutely misleading. But I find it funny in one way. Maybe it isn't.
