Research into similar products - Ad Review

I am have almost finished my album advert for my music video however i have been researching other thing i could include to make my advert more effective.

I looked at Metallic's album advert and what i've noticed is that it features reviews from different media outlets. These reviews consists of stars which is a common way to rate a song as it is easy for an audience member to identify its scores allowing them to know if it is popular or not. I think i can use this on my advert as this will help my audience to know whether the album is good and it will make my advert look more realistic as it has been rated by other people. The two common raters that give out rating are The Guardian and Q magazine so i have decided to use them on my advert, also as they are the most common raters the audience will identify them and become more inclined to buy the Album.
