Greatest Hits

Greatest Hits is Waterparks 4th album. It was released on Friday, May 21 and includes features from other artists, such as De'Wayne Jackson, My Chemical Romance's Mikey Way, and Dallon Weekes from I Don't Know How But They Found Me. This is also the first Waterparks album where Awsten is specifically listed as producer, despite being heavily involved on the others.

The title "Greatest Hits" was first announced after the release of the 2nd single, Snow Globe. After the album's announcement, many people on twitter rediscovered the interview where Awsten mentioned if Waterparks got to G they would call the album "Greatest Hits". For this album Awsten dyed his hair blue, yellow, and red/pink in different patterns.

There were 6 singles released before the album dropped. Each one of them was announced in a different way. The singles were: "Lowkey As Hell", "Snow Globe", "Numb", "You'd Be Paranoid Too (If Everyone Was Out To Get You)", "Just Kidding", and "Violet!".
