q: pathnames of descendants whose (names of it as lowercase ends with “.mp3”) of folders “” of drives whose (type of it=“DRIVE_FIXED”)
E: A singular expression is required.

Thanks in advance,

Try this instead.

pathnames of descendants whose (name of it as lowercase ends with ".mp3") of folders "\" of drives whose (type of it="DRIVE_FIXED")

I would also recommend not having this run any closer together than 12 to 24 hours because of the way the decendants inspectors works. It can cause serious complications if it’s not spaced out.
