What piece of music can you play over & over?


I had discovered a new opera a few years back that I can't believe I played over and over for six weeks straight without changing the disk once.
I believe this means the composer was a genius, who else but Mozart can do this, and the opera was Abduction from the Seraglio.
Have any goners found themselves in the same situation.
