Need advices for a little web game (Rooms and players list)

Hi,

I’m making a little game where we have to give the name of the song playing.
Here is a part of the design, I’m currently focusing mainly on the lists on the left and right. However it feels really off and I’m not satisfy but I don’t know why.

I looked at plenty of designs and tried to replicate them, but for some reasons it always looks awful.

I would like some advice to understand why it feels bad.

Thank you!
