I asked my native english speaking friends and they all said I’m not using “listen up” the right way. Here’s the lyric:
Jane won’t talk about it
But every night she feels like crying
And there’s no one at home to listen up
I went to online dictionaries and they all point that “listen up” is generally used in a command context. But they’re keen to admit that only the “usual” use case.
Anybody has used it the way I’m using it? To mean when somebody listens with attention.
