I'll say my 2 cents real quick about Neon Lights and future singles.
Demi is NOT at the stage in her career where she can AFFORD risky singles. She needs to keep the momentum going. I'd rather her gain more radio presence THIS era, THEN try to dab into risks more but still add that radio flare until she totally has control of releasing a single that isn't radio friendly, yet still have success.
Before people mention SKYSCRAPER, that was her "comeback"/1st single, which relatively always do well.
SINGLES = radio = boost in album sales, the ultimate goal for singles.
MORE SALES IN ALBUMS = more people interested/paying attention to her and her music.
With that being said, I want RDC as the next and final single. Besides, she's NEVER had a single of her own with a feature. The video would kick ass. Especially since Cher is joining the tour now.
Don't be surprised if they start filming next month
She's been playing it safe all along and RDC is just a childish peace of garbage so no THANK U ... I want either two pieces, nightingale, or even warrior since she kills that one live ! 
Neon Lights is proving everyone wrong!! .... "be still my HEARTcause is freaking out" her usage of heart... Indeniable power! This is the reason why Neon Lights became a hit and Made in the USA flopped.
It'd be cool if we hear your opinions/views for fourth singles/moving on from the DEMI era in terms of singles there. 
This is doing great even though two of the biggest radio stations in the US haven't added it yet! 
Congrats Demi!
