It seems redundant to me to put the same artist credit more than once, such as when the composer and the conductor are the same as in this example:

Is that something I should correct?
I think it’s reasonably useful to specify it’s not only a composer, although I wouldn’t say either way is wrong.
I agree, and note further that the cover designer found it important too, listing him twice.
(Wonder if anyone has put out an album of John Williams playing guitar arrangements of John Williams, just to maximize confusion. Good thing I don’t run a record label, I’d so do such things…)
