Finding "Lost" Music

[Jim Wickman]

I discovered this morning that two albums which are in my iTunes 
Music folder are declared to be missing by iTunes -- the dreaded 
exclamation point  ( ! ). So I went through the routine of Cmd-I, 
search, click, click on info window, go on to next . . . Tedious

That set me to wondering if there's some way to get iTunes to 
re-recognize albums instead of having to go tune-by-tune.

Suggestions?
