What piece of music can you play over & over?

Tvad - That is a great track. Its too bad the rest of the ablum doesn't live up to it. In fact I think that record might set the standard for albums with one great song surrounded with inane unlistenable fill. But that is one really great song.

Coltrane - Blue Trane, Monk - monk's Music, and the original version of Take the 'A' train, which in addition to being a jazz classic is also an almost perfect three minute pop tune (which of course it was too).

On your "eight hours of the same cd": I was in England about fifteen years ago and there was a case in the papers where a woman was suing her neighbor in an appartment building. She had been loudly playing Whitney Houstan's I Will Always Love You over and over again all day long for a month or so until her neighbor burst into her appartment and threw her cd player out a fifth story window. The judge dismissed the case on grounds that she had incited her neighbors actions herself by torturing her neighbors with "that absurdly annoying song".
