"The summer hits of 2001 are making about as much money as hits from previous summers, but they are making it quicker, making more of it that ever on opening weekend. Movies are opening on more screens, generating staggering grosses, and then plummetting off the radar. Many executives of the Hollywood see this trend, which the call "front loading," as a fundamental change in the way the summer movies are watched."
Songs that are marketed to be summer hits are very common, and often feature an upbeat tempo and descriptions of things such as relaxation outdoors and beach parties. These are songs considered ideal listening during summer activities. These intentional summer hits are most common in country (particularly country pop) and mainstream popular music but are much less common in rock.
The opposite of a summer hit in the music industry would be a Christmas song, a category that usually incorporates general winter songs as well.
