Firstly, i believe music started with song, not music. that being said, music as an asthetic entity tends to be enhanced more by musical lyricism than anything "meaningful." and who's to say that music without lyrics has no meaning? everyone reasonably capable of thought can recognize a sad/happy/suspenseful tune no problem. listen to large amounts of classical music, and it's like learning another language; you recognize the instrumental sounds of war, of peace, of love.
