The time I like listening to music most on headphones is, I have a game I play with my brother, he's a musician as well.And he sends me MIDI files of keyboard pieces. So, these are pieces where I just get a MIDI file; I don't know what instrument he was playing them on; I know nothing about his section of the sound of the piece, and then when I'm sitting on trains I do a lot of train travel I turn them into pieces of music. And I love to do that; it's my favorite hobby.
