Freezing up while refreshing

Thanks for the reply. It may have had something to do with the tags, but I wasn’t able to fix it. I had run MP3Gain on my files, which I guess uses tags to level the volume of the tracks, so maybe that rendered a tag it didn’t like, but I wasn’t able to identify it. However, I just got a new laptop (for unrelated reasons) and reloaded all my music from a backup drive, re-ran MP3Gain, and everything is working fine.
