I opened up iTunes and received the message "Updating iTunes Library." I'm not sure exactly what it's doing (gapless playback? finding album art?), but it's taking very long. It's about halfway done, but it's been at least 15 hours. Ugh.

Anyone else have this problem?

I just keep avoiding it, young money.

just had this message pop up the other day for me and I let it go.

It's been two days now. almost 3/4 done. oof.
