"THIS AMERICAN LIFE": Moving, frank, and funny stories are at the heart of this much-obsessed-over radio show, as is congenial host Ira Glass, and his sweet, bespectacled voice. Yes, we said bespectacled voice. It is like his very dulcet tones are wearing a pair of handsome frames. Anywho. You love the perennially smooched-on series, you'll covet the new app, which was just announced. PHONE-BASED TALES: It's $2.99, and comes with, and we quote, "(o)n-demand access to every radio episode we've ever produced." Yes. That's what they said. Happy revisiting those 217 favorite stories from the long-ago past, TAL fans.
