fix title_mismatch false positives due to window title not being updated by Spotify

[gmdfalk]

Somehow, Spotify won't always publish the window title to the window manager, leading to just 'Spotify' being reported by wmctrl. This, in turn, leads to a false positive in ad detection. Pausing and playing the song again properly broadcasts the window title again. I can only produce this issue on one of my machines so it might be some weird system issue.

I sometimes have false positives too. I am not sure the reason behind it but it happens when I start playing a song manually (in contrast to automatically advancing to the next song). This fixes the false positive temporarily: pause, seek to very beginning of the song, play.

Thanks for blockify :)

Same problem here. The only way to solve this for me is stopping and restarting playback which results in updating the window title. Would it be feasible issuing "stop - start playback" after each (first) ad-detection and then start ad-detection a second time?
