ITunes only responds about every 20-30 seconds

Question

I fear this may be too broad a question, but I thought I'd ask it just in case there's a common solution.
Basically, most of the time, let's say I double-click a song and iTunes starts playing.  Then I try to click something else, but it's like iTunes is frozen for about 20-30 seconds.  The music isn't interrupted; I just can't DO anything, whether it's select a different song, pull down a menu, hit "pause", click in the search box.  Even the progress indicator on the song stops moving, then jumps ahead 20-30 seconds.  Then it responds for a few seconds, then freezes again, over and over, pretty much all the time if I have music playing, which is most of the time.
Otherwise, the PC runs fine.  I'm about resigned to getting rid of iTunes for some other music-playing software that works better on a PC; it's just that I'm so comfortable with iTunes and I have everything organized just how I want it and I really wish it would just work properly.
