Music videos are primarily made and used as a marketing device to promote the sale of music. They allow artists to engage audiences with the song's meaning and narrative. Having an online presence through YouTube is important for widening an artist's audience and exposure. Successful music videos like Beyonce's "Crazy in Love" and Justin Bieber's "Baby" helped propel their songs to commercial success through compelling visuals and viral popularity online. Creative music videos that entertain, educate, or inform audiences are important for convincing people to purchase and support an artist's music.
