@leocg Yes, that's true. But it doesn't provide the same features as background music does (pausing automatically when sound from another tab is played, resuming automatically when sound from another tab is stopped, etc).

Connecting whatever music streaming service you use to Opera GX, and having it as one of the "background music" options. One of the potential ways it could operate is by choosing a specific playlist to automatically play.

This would be an good feature, because there is only 5 tracks of music available right now, and they are all instrumental. I, personally, almost always have Spotify playing in the background while I work, which takes up extra resources on my computer, and needs it's own space on my taskbar, when I usually need ~5 different programs open. This would eliminate those obstructions.
