What she means is she has to have her two bobs worth.
Ben reckons he loves music more than JJ because he takes the time to learn all about it and actually writes music. JJ reckons because he downloads more tunes so he loves music more, iffy says you can not measure love.
It is the daft comparisons they come up with that make me laugh. iffy on about if you love your house and then someone else comes in and says they love your house then that is the same, and that is the same thing. (wrong of course)
Ben obviously has more real passion for music, JJ just likes the end product.
