Now Playing is a pixel exclusive feature that works in the background without triggering assistant. It seems like OP is trying to trigger this feature from the foreground? Which I think is a good feature but I doubt Google would let any phone use this because it sells pixels and is proprietary.
OP is IMO quite clearly trying to tell google assistant on a not-necessarily-pixel device to identify the song, which should be a kinda standard feature for voice assistants.
