Blip IS into music, so it's not a hypothetical question for her! She loves the blues, particularly John Lee Hooker - we think it's the wailing guitar she goes for. Suits her feisty character too.
In her highbrow moments, she loves high female voices, particularly in choral music, and one of her favourite pieces is Pergolesi's Stabet Mater, which I mention (a) because it's lovely and (b) because other people might like to try it on their puds.
