Hi tofumatt, Good to know you are interested in the FxOS's api about the media remote controls. Those two issues are really good questions and probably also two of the top 5 that people care about if they are developing some media apps(like you do).
The first one: https://github.com/mozilla/high-fidelity/issues/40 How the music app tell the lockscreen to show the metadata is using the api called IAC(Inter App Communication)[1], and Tim is correct, currently only Certified Apps can use it, maybe in the future the platform will enable the capabilities for the Privileged Apps but I am not sure. The second one: https://github.com/mozilla/high-fidelity/issues/41 If I understood correctly, you should be talking about the bluetooth profile called AVRCP(The Audio/Video Remote Control Profile)[2] that has the capabilities to control the media players via bluetooth protocols, I am glad to tell you that we do support it in FxOS! AVRCP 1.0 and 1.3 are both supported so it means the play/pause commands you are looking for can be implemented, by listening to the system messages[3]. And I think you already found the shared module we use in gaia for the remote controls[4], it was implemented to handle both IAC and AVRCP since there are both controls outside of music app, you could probably pick up the system message part then adopt it to your app, and should be able to fix the second issue.

AFAIK the features you are looking at are implemented with IAC API, which is certified app only. So unfortunately as an 3rd-party app, you can't touch these bits in FxOS, for now. I know it's frustrating to find out that, but I can assure you that Gaia developers are equally disappointed to work on a coupled-to-system and certified-app-only solution (as opposed to general solution) when being pushed by external feature requests.
