Prom is coming up this Saturday, and "The Mixtape" is back just in time for the big dance. A&E co-editor Sindha Agha has compiled some of her favorite dance tunes for the ultimate prom mix. Whether you need a little something to keep you awake after the 5K as you get ready, music to get the dance floor going, or tunes to keep you going at post prom, Sindha's got the mix for you.
