Talent

Just about any pop singer (Katy Perry, Mariah Carey, Cher, etc) can make a great song in a studio full of sound engineers who can auto-tune and digitally correct their sound.  This is called technology.

But THIS, ladies and gentlemen, isn't technology.  Its called talent:

Technically correct LIVE singing filled with dynamics, emotion, control, and restraint.  These are attributes of talent that can't be duplicated with technology during a live performance.

Kudos to Lady Gaga for a beautiful tribute to these classic American songs, while simultaneously showing the world she's much more than just a pop singer.
