Can the Airport Express play music if it is connected to the network by wire only and not by wifi?

Hi,

I would like to add an Airport Express to the second floor and the wifi range is not strong enough from my wifi router located in the ground floor.

However I have ethernet plugs in all rooms connected by wire to the router. So I was thinking to plug the Airport Express via wire to my ethernet plug.

The goal is to have this Airport Express listed with all the others located in the ground floor that are connected wirelessly in my Airplay speakers.

Thanks
