This remix probably came about when Baauer opened for Nero in Europe last month.
Update: Soon after posting the Baauer remix I visited the MTA Records Soundcloud and found this absolute gem. It's the same Nero track but this time it's remixed by Club Cheval:
Music is entirely a subjective experience but when I compare both of these tracks I think the Club Cheval remix wins hands down. It's also probably the best remix I've heard in quite a while.
