Dude you're seriously the only one that still thinks this is Lana. It's clearly NOT. Lana's never ever used a voice like that and if they were to use her in a song, why would they have her make it sound so different? Just stop.

I listened to the Audra Mae song and there are parts where the vocals sound exactly the same so it's her.

This is a Smash waiting to happen. Avicii never disappoints.

Also, This clearly is not Lana. So..
