Hi!

I'm a premium user, using web player due to corp. firewall not allowing me to use desktop app. 

The information of some tracks are getting stuck in the player display, the player goes on playing the following songs of the list but shows the old cover, title and artist.

Then, some tracks later, the player is updated with the actual track; intermittently.

Also, another issue is that some times it keeps the old song information and goes on playing (as before) but the play button is like when it is paused (it displays the triangle to play the song rather than the pause symbol, and pressing play doesn't have any effect). Passing to the next song refreshes the player and the correct information is shown. 

I'm using Spotify Web Player in Windows 7, with Chrome 55.0.2883.87.

I've already allowed [*.]spotify.com into chrome settings (flash option).

Also, Chrome Dev Tools is showing some notifications.

I attached the screenshot with warnings while playing tracks.

And also another screenshot showing warnings just after I loaded web player page.
