Add another speed between .5 and 1
I don't know that I'll ever want a song to go faster, but slower is helpful for learning. However, .5 is a little tooooo slow for anything but the first pass through a song; it would be great if there were at least one more slow-ish step.
Good news, YouTube changed their player and added a speed of 0.75. We just did some jamming in the office and it’s perfect!
