Yeah, you're right. That was my initial thought too, but since this behavior "started" after I installed mIRC 6.1, I thought that it was an mIRC bug; but now I know that it was just a coincidence.
Only a set of songs I recently ripped from a sampler CD I got do this and, after downgrading to 6.1, I tested the identifiers and they return the same values they do in 6.11/6.12. And now I know for sure that it's not mIRC's fault.
