I like Wake me up. I was going to say levels but that does not have many words in. I know アヴィーチー tends not to put many words in his songs but in a song I like words not just music. did like Wake me up until I saw the video.... then I loved it because the message was that everyone has a place in the world that they fit in and あなた will find it (I think that was the message anyway!) so that's why I choose Wake Me Up as my favourite song
