excellent choice my good friend porkie.

i'll go with "everything in its right place" by Radiohead

One of Glenn Branca's pieces with a full symphony orchestra.

first calla album is a "nightly" one,but the last track sometimes wakes me up,which is not a nice thing to do....i must remember not to put it in the playlist....

if by end of the day you mean before bed, then here is a list of listening for the appointed o'clock

keiji haino - next let us try changing the shape
roy montgomery
windy & carl
nijiumu - era of sad wings
tara jane o'neil
charalambides and christina carter's various projects

on end of days I like to play everything
