Hello,
I remember I once installed a script that allowed you to replace
what you are listening to with a custom message or fake title song.
I wasn't actually listening music but to my contacts it would appear as if I was, except that I could set a custom message with the little headphones icon next to it and the text was in blue... exactly like when someone is listening to a song and has the
Show others what I'm listening to option
enable.
I don't know if this script still exists but it was really cool.
Thanks for your help!
