The last verse of Psalm 104, based on how the music behaves, puts itself outside the domain of the rest of the Psalm.
Check out the music here - note there is no mid point rest (atnah) even though it is quite a long verse.
This is worth comparing with other psalms at the end of a book where the last verse is a doxology. Here, the final condemnation is combined with a doxological statement.
Psalm 105 likewise has no atnah in the final verse. And neither does Psalm 106. (Hmm I just noticed a deficiency - my heading does not include the psalm number - must change the program! [done])
