Thanks a lot for the clarification, that sounds really cool! I didn't know she knew that much about music, but it could always be a linguistic mistake for 24/7, which is a figure of speech used a lot, meaning "Twenty-Four hours a day, 7 days a week." It could be talking about the constant role that music plays in her everyday life... ^-^
Okay, I know I'm stretching, it could be something totally different. I think the idea of it being a date is a really great one too, ya never know.
