How long should you wash your hands? There's a tune from every decade that can help

(CNN)Coronavirus cases are climbing in the US, but health officials maintain one of the best ways to prevent it from spreading is by washing your hands.

Simple enough, right? Wrong.
There's a proper way to do it. And it doesn't include rinsing your hands for a moment and a half, wiping leftover droplets on your jeans and then calling it a day.
    Instructions from the CDC say you should be lathering soap on your hands for at least 20 seconds. To help you keep track of time, the agency suggests you hum the "Happy Birthday" song twice.
    But no one wants that in their head if it's not a special occasion. So instead, we compiled a list of songs with a tune from each decade to help you jam out as you're scrubbing off the germs.
    And for these songs, there's no need to just hum.

    The warden threw a party in the county jail
    The prison band was there and they began to wail
    The band was jumpin' and the joint began to swing
    You should've heard them knocked-out jailbirds sing
    Let's rock everybody, let's rock
    Everybody in the whole cell block
    Was dancin' to the Jailhouse Rock

    The 60s: 'My Girl' by The Temptations

    My girl (my girl, my girl)
    Talkin' 'bout my girl (my girl)

    Next we're movin' on
    He was with me, yeah me
    And we'll be movin' on
    An' singin' that same old song
    Yeah with me, singin'
