For any partition that you mounted read-only in order to run fsck, yes. This generally will only mean the root partition.

When a normal Linux box checks its root partition (which is mounted read-only) at bootup, and changes were made by fsck, it forces a reboot for just this reason.

Completely unmounting the music partitions before running fsck (as per my post, above) doesn't require a reboot afterwards.
