Agreed. Mozart's clarinet concerto used to be a big event in my life. Something to sit down with every now and then for a quiet half-hour and really savour. Now I seem to hear at least a snatch of it every day. Mendelssohn's violin concerto suffers similarly. But I have at least learned, from its incessantly-repeated airings, that Elgar's cello concerto is actually crap. Except when Jacqueline Du Pré plays it, of course.
