I don't think it's me you can hear

An old man on the bus just asked me to turn down my ipod, asking "Why can't people realise that nobody else wants to listen to all that thumping bass?". Now I hate this too, so I obligingly turned it down, but I couldn't help feeling a bit confused as I looked down at the screen. I didn't think Tchaikovsky's Sleeping Beauty Suite was known for its thumping bass.
