Song by Sonic Youth on their album Daydream Nation.
Well, I would suppose it is only really a song in the John Cage sense of being a song. Sheet music might fall short. For that matter, a description may fall short, as the lyrics are not really all that clear, and it is not "written" as such.

But here goes:

A haunting, reverbed-out piano part accompanies a series of answering machine messages left by Mike Watt of fIREHOSE, who is calling from Providence. The messages seem to relate to the location of Thurston Moore's mota, and the memory problems associated with the use of such. Possible locations mentioned in the exchange are a trash can, or in a van.
