2. Extension of income
Some record companies make music videos to generate money, in some cases
artist/record companies will release songs before music videos to see if the
song will be successful and if the song is they release a music video version
afterwards.
The music video can also be used to promote the artist/bands identity, many
artist can be remembered because of their memorable music video for
example Brittany Spears and Gorillaz.
3. Promotional
Music videos can be used to helps sell the song and get it stuck in the
audiences head so the remember the song and the video, it can also help the
audience understand the song better especially is the song is narrative based,
a good example is R Kelly – Trapped in the Closet. It can also be used to show
of an artists talents or to just plainly entertain the audience. It can also be
used to promote the song which then promotes their album if they release
one.
4. Synergy
When musicians/artist release music for movies it is synergy, Twenty One
Pilots – Heathens and Wiz Khalifa – See you again are examples of this, they
used clips from the movies that used their song which helped promote them.
This works very well when they film becomes popular, Adele – Skyfall was a
bit different because when it was announced that she would sing the opening
for James Bond both the film and singer.
