When you play UNO, have some goofy or action-like background music

It makes the whole thing way more entertaining. Like you go in a faster pace or even match the whole vibe of the song. Makes UNO way more fun, It also goes for any other card game. I would choose the more underrated Undertale and Deltarune soundtracks, those short tracks have that silly vibe to it which can make a game more entertaining.
