Strange error and immediate failure

[Sawtaytoes]

I'm running into an issue with abcde, but I'm not certain of the contents of this disc as I'm ripping it from a CLI-only Raspberry Pi. I'm 99% certain it's only a music CD.

Version:

$ abcde -v
/home/pi/.abcde.conf: line 14: musicbrainz: command not found
This is abcde v2.9.3.
Usage: abcde [options] [tracks]
abcde -h for extra help

This is the error I got trying to mount the disc:

pi@optical-drive-3:~ $ sudo mount /dev/cdrom /mnt/cd
mount: /mnt/cd: can't read superblock on /dev/sr0.
       dmesg(1) may have more information after failed mount system call.

Not sure how I'm supposed to mount audio discs in CLI.

Is 2.9.3 the latest?
