3 mashups.

I'm really in love with this one because Beyoncé is one of my favourite artists in the world and I think that the video is so worked.

I like this one because these kids used songs of different musicals of the world and created a fantastic mashup of that.

And finally... This one is my favourite. Just because it's if Queen and the voice of each singer in this video it's just perfect to sing the songs.
