Spotify appearing on lock screen? Proactive?

[applefanboy4]

so I've noticed that more than once a day I will click the sleep\wai button on my iPhone and the lockscreen will appear but it's just jy background and in the white font where the time usually is when you wake the phone will be the word Spotify and the rewind and fast forward arrow and then a volume controller. This is even when I haven't used Spotify in awhile and when Spotify is closed on my phone. And happens even without headphones plugged in. It appears to be different than proActive as its near the top of the screen, there's no small app icon. Spotify is one of my most used apps but I don't see it doing this at specific times as with proactive when I plug in headphones and Spotify appears in the Lower left, this is different. Is this a glitch? Would using Spotify on my MacBook and then checking my phone be the issue? A lot of times I'm listening to Spotify on my MacBook.
