And then you’ve got this masterpiece which only exists as one performance at the 2014 Grammys: a Radioactive-MAAAD City mashup. They never made a studio version of this, but man was it beautiful while it lasted. Even CBS constantly cutting back to Taylor Swift’s painfully awkward dancing couldn’t ruin the atmosphere. The lyrics, the melody, the energy, everything mashed up perfectly and we’ll only be able to hear it on YouTube.
