If you had to listen to one artist, and one artist only, for the rest of your life, who would it be?

So the evil witch, Abaddon, appears before you out of green flame and billows of smoke in all her horror and casts a spell on you. From this day forth, until the day you die, you can only listen to one artist; the next you happen to hear.

However, you are fortunate, for as soon as this witch leaves in the fibers of her horrid laughter, the angel Sidhe comes to you in sunlight and clouds and offers you to choose who it is you hear next. Who is it you choose?
