I'm guessing it depends on the music and videos.
If you made them yourself they are basically irreplaceable and RAID will
replicate any bitrot to the other copy undetected.
Even if not, they still represent a great deal of time to accumulate
and then to replace. Most of mine have been recorded* from Cable TV
programs, and replacing them would require either waiting a huge amount
of time for all of them to be re-broadcast (if ever), or else purchasing
literally thousands of Blu-Ray disks.
Again, I cannot possily reiterate that RAID is #NOT# a backup solution.
On several separate occasions I have lost an entire RAID array. Each
involved a completely different type of failure. In two cases I was
able to manually recover the arrays with only minimal loss of data. In
one, no data recovery at all was possible (a Windows system). In every
other case I had to resort to backup. One of those times, it was the
backup system which failed, and then DAR really saved my butt, as it has
done on a number of occasions when the corruption was far less extensive.
