Making a wedding gift. Need help. Answered

one of my best friends is getting married in September.  I've been trying to come up with a cool gift to make them, but am running out of ideas.  I was going to try to make something for their new home they just bought, but they got situated real quick with new stuff so it's kinda difficult to figure out something they don't already have or that will fit somewhere in their new home.  I wanted to make something that they could/would use, something that has some sort of function, but since the "home gift" ideas are sorta low, I was thinking something more sentimental.  A few years ago I made a gift for my brother, pieces of wood with a waterslide decal of his daughter and her name woodburned into it (I can't upload photos now for some reason otherwise I'd show).  I was thinking of something like that... BUT the husband&wife to be are also into dance parties and that gave me the idea of wanting to do something with LED lighting strip that goes with music played.  I'm thinking one or the other or both or something entirely different.  If anyone has any ideas for a wedding gift for a couple who likes dance parties/music/photos/beer/food/etc... I'd greatly appreciate it.
