"Don't Let Me Go," a new track sung by One Direction member Harry Styles, made its way online today. Is the tabloid favorite/Taylor Swift ex gearing up for a solo career? Is he ditching his bandmates?! IS THIS THE END OF 1D?!?!

For now, stay calm. All we know is that Styles collaborated with producer Sam McCarthy on the Ed Sheeran-esque pop/rock ballad. 

Louis Tomlinson said 1D is planning to drop their third album by Christmas. But what happens with Styles after LP3? A few theories:

No. 1: Styles preparing to launch a solo career, a la Justin Timberlake.
No. 2: He recorded this years ago, but it just made its way online.
No. 3: Styles recorded it as a demo track for another artist. It happens all the time (David Guetta originally recruited Sia on "Titanium" as a demo for Mary J. Blige).

No word from Styles, but the track is good. And when boy band members have good solo material (JT!), they tend to not return to their day job.
