I like accordion. To me, the sound of the accordion is the sound of happiness and a party. For another side of the accordion, see if you can get hold of Nonesuch's Tango Project recordings from the 1980's.
(I wonder if they made it to CD.)

I have just started a thread called Tune Add: The Merry Nightingale. I created a MIDI of a 17th C. round and I chose the accordion sound for one of the voices. I wanted three distinct lines, so I selected recorder,harp and accordion. Give it a listen when it appears.
