Does it ever seem like sometimes when you're listening to music, sometimes you can swear the song is being played a bit faster, or that it seems like it's going by faster. (Sometimes if I hear a song early in the morning just after wakin' up, it seems like it's going by a bit faster. It could be that my brain is a bit slower, because it hasn't had time to wake up yet).
The song in this video has been ever-so-slightly sped up (just like what I'm talking about), but it's also played at a slightly higher tone.
