The movement of music from physical discs to digital resources managed on a computer has had an effect on the listening habits of users. We explore using the potential of the innate synaesthesia that some people report feeling between colour and mood in a novel interface that enables a user to explore their music collection and create musical playlists in a more relevant way. We show that there is a reasonable degree of consistency between users' associations of colour and music, and show that an indirect descriptor can aid in the recall of music via mood, making playlist generation a simpler and more useful process.
