I've heard this effect mentioned several times, but if it applies to me is not strong enough to be obvious. (Then again, it's not like I tried to test it statistically.)
Possibly, at certain times of the day music might make me more productive, by making it easier for me to stay awake.
(OTOH if I listen to music while concentrating on something else I usually can't remember any of the lyrics afterwards.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
