In a  music video it is a must that the music artist is appeared regularly in the video as that need to promote themselves. The more they show themselves the more the viewers will recognise them which will gain their popularity. If we don't not see the artist they cannot promote themselves as we don't not know who they are.

 Many people watch music videos for their own entertainment and the joy of watching the favorite's artists .

Music videos can help promote products , for example Lady Gag promotes cans of coke and virgin mobile. This is good for the company as Lady Gaga is a massive idol today so for her to promote their products can boost their earnings.

Many music videos have links to films as well which helps both boost the artist fame but also the films fame for  example Celion Dion My Heart Will Go Hone if featured in Titanic.
