Classical "Performers" versus "Composers"

Hello,
I just upgraded to 1.8 and am, for the most part, happy. Howard, I’ve been running into a difficulty with my large classical music collection. I find that some composers are “split” into “Performer” and “Composer.” For example, half of my Beethoven albums appear under Beethoven as a “Performer,” and half appear under Beethoven as “Composer.” I want all of them to be under Beethoven as the Composer. Any suggestions will be appreciated.
Thanks!
