Kanye knows that the Psalms are meant to be put to music. We might read them as poetry today, but the Psalms were designed to be memorized and sung by the Israelites together.
Surprised? Then you probably missed Psalm 150 completely:
Praise him with trumpet sound;
praise him with lute and harp!
Praise him with tambourine and dance;
praise him with strings and pipe!
Praise him with clanging cymbals;
praise him with loud clashing cymbals! (150:3-5)
The message is pretty loud and clear. We're even told which instruments to use (Psalms 4 and 5 help us out there, too).
Psalms could be sung in a variety of contexts: at royal events, before battle, and at parties and festivals. Bottom line: singing God's praises was a privilege, not a chore:
"Now my head is lifted up above my enemies all around me, and I will offer in his tent sacrifices and shouts of joy; I will sing and make melody to the Lord." (24:6)
This shouldn't sound unfamiliar. After all, we still do it today. Maybe not with Psalms, but we sing cultural tunes at presidential galas and inaugurations, and we have certain music associated with battle and other military events.
