Commerical Jingles Are Hits of Tomorrow?

In Demolition Man, the future generation was singing along to old commercial jingles like Meow-Mix. It is 2010, will this prediction come to fruition? It seems that lately commercial jingles seem to be a dying breed because major ad companies are recycling hit tunes from the past. Perhaps society attention span and adoration for original music will surmount to a 30 second jingle for Ala Seltzer as the top hit.
