Neon Lights served it's purpose well, it's charted well (considering the poor airplay) and it's boosted her album sales.
No one really knew who Demi was in the UK before Heart Attack and Skyscraper, so it's good that she is continuing to establish herself.. I think "Really Don't Care" is going to smash.
