Meaning of the musical term 'Deep Cuts'
I have heard the term 'deep cuts' to refer to album tracks. I always assumed it meant songs not good enough (or commecial enough) to be released as singles. I also thought this was the definition of 'b sides', but according to a few sites online 'b sides' are tracks that where not on an album. I have several singles where the 'b side' track was part of the same album as the single so it would seem that definition is not always true.
So -- What is the definition of 'deep cut(s)'?
Note -- Not sure if this belongs here or cafe society, but I assume there is a factual answer so I will put it here. I am sure a mod can move it if deemed necessary.
