Music videos are important for promoting new singles and keeping artists' songs in the charts. They advertise the single, help the artist gain recognition, and allow other products to be promoted like perfumes or merchandise. Brands also partner with popular artists to advertise their own products through product placement in music videos. This has become necessary for artists and the music industry to make money, as album and single sales have declined due to piracy and streaming services. Music videos are one way for artists to release new music and multiple products at once, while also providing branded entertainment for companies.
