I have a Car profile that when bluetooth/power connected launches Spotify and plays the current playlist. That works quite well.
What I now want to do is add the displaying of track info when the next track starts. I know Spotify already does it but it shows in the menu bar which is displayed too small and too quickly to be seen by me while driving, so I'd like Tasker to display it larger and for a greater duration.
I am able to detect the next track using the respective Media Utilities plugin event and then display an HTML popup that includes %MU_TRACK and %MU_ARTIST, among other variables... however none of the variables populate, I just see the literal "%MU_TRACK" text. So it appears that Media Utilities variables aren't available even when tracks are playing. I've also tried using Google Music with the same result, so it's not specific to Spotify.
Any ideas on why I can't access the MU_* variables from my tasks?
However, I do see that there are some local variables available that seem to work %track, %artist, %appname, %isplaying and %coverart_uri but I wonder why the latter documented variables don't work.
