Abi is smart

She likes to listen to her music when Daddy drives her to school.  Of course, Daddy wants to listen to his music.  So Abi came up with a very reasonable suggestion.  They would listen to 6 of her songs followed by 6 of his songs.  Sounds fair?  It turns out it takes about 6 songs (time-wise) to drive from home to Abi’s school.
