Music in the studio on or off?

I have a lot of music in mostly cds, my Iplayer in packed and even some albums from collected as a teenager in the 1960s.  It doesn’t get played as much as I would like;  as I listen to the Radio 6 music during the day. However, while working I do find that distracting; so have taken to selecting instrumental music from my collections; but I don’t have very much … Brian Eno, Mogwai and Minor Victories are pretty much played back to back.  I have discovered that some sound tracks are pleasant as background although Twin Peaks is haunting almost disturbing if I remember the program and On the waterfront by Davis Amram is well played.  

I am not sure if the music has improved my work per se but the routine of switching off the radio, choosing and playing while preparing my workspace has added another layer to a nice experience and I have enjoyed working more … and wish I had thought about it sooner.
