Taylor Swift

A big consistent name within the music industry and one quite a controversial one that could definitely boost your "Reputation" it would be quite difficult to talk to her considering she keeps going "missing" while she lurks around, the best way you can even contact her is going to your manager and hoping you may get a respones. This could be a hard collab to get but you decide to try anyways what could possibly go wrong.

You message your manager the next day to see if this is a thing he could set up he's unsure but after a bit of persuading he eventually agrees and tells you if he gets a response.
