No. We will not go gently into this Halloween night.
First of all, that would go against all things Halloween. Second of all, it's much more fun to debut a mystery box series on Halloween then not.
AM and FM are ways of broadcasting radio signals, but in terms of this mystery box series, AM and FM will describe the two box categories. AM and FM boxes will always have different content. Prices and availability will vary depending on the drop, but in general, AM boxes will be the less expensive and more plentiful of the two. (Don't worry, both boxes are sweet values.)
Each AM/FM box description will include a short song quote. That's it. They are mystery boxes after all.
These will drop October 31st at 9pm EDT. AM boxes are $39, and FM boxes are $65. Supply is limited.
