Missing Song Title

[HudsonReid]

When I am using this library, setup and everything seems to go smooth, and the first song correctly gives me the artist and song name. However every subsequent song name after is returned null or something went wrong but the artist return value is perfect every time. I figured my token was expired or my calls were bad. However when I debug and add in the print_response(r) for r = sp.currently_playing(). I can see in my serial monitor that all the correct information is coming through. The weirdest part, is that if I switch platforms (ex. from phone to browser, browser to windows app) It immediately picks up and outputs the correct info, then every song after is messed up again. Any thoughts?

I will definitly take a look at this, i havent updated the library for a long time and the spotify API is updated quite frequently with a lot of changes eg in format etc. so that might be it.

I tried to reproduce your error with this, but it switches with new songs if you have any idea why you get your error feel free to contact me also over discord if you prefer could make a call there aswell if needed. If you are able to you might also try to print the data in the current_artist names function or the current track function
