In my collection of classical music I have a range of pieces which last 6, 7, 8 and 9 minutes.
The piece by Bach lasts 8 minutes and the CD lasts longer than the piece by Holst. The piece on my iPod is longer than the piece by Beethoven. The record single lasts for 7 minutes and the LP album does not contain any Holst. The piece by Butler is on the iPod.
Can you determine which piece of music is on which format and how long each lasts?
