It's like youtube music but its only for certian groups or bands like Wiz Khalifia is not on Vevo beacause maybe he did'nt sign with Vevo but its like Youtube but Vevo is just music videos only music vedios youtube is music,videos,and more .
I love this app, because it has almost every music video and it adds new videos everyday. You can discover new artists and hear songs that you like. The only problem is that there are some videos that are very explicit, so when around children, proceed with caution.
