TAMPA, FLA. - Mitt Romney began his Republican National Convention (RNC) speech off on the lighter side Thursday night, joking that his playlist is better than running mate Paul Ryan's list.

During his address at the convention Wednesday night, Ryan, 42, zinged Romney, 65, on his musical tastes, saying, “There are the songs on his iPod, which I’ve heard on the campaign bus and on many hotel elevators.

"He actually urged me to play some of these songs at campaign rallies.  I said, I hope it’s not a deal-breaker Mitt, but my playlist starts with AC/DC, and ends with Zeppelin," Ryan said to great fanfare.

On Thursday in his presidential nomination acceptance speech Romney responded.

"But Paul, I still like the playlist on my iPod better than yours," he said.

The back and forth exchange across the two evenings reinforced Ryan's the notion that even though Romney is old enough to be Ryan's father, they share the same vision for the future of the country and they truly are "America's Comeback Team."

"A generation apart. That makes us different, but not in any of the things that matter," Ryan said in his speech Wednesday. "Mitt Romney and I both grew up in the heartland, and we know what places like Wisconsin and Michigan look like when times are good, when people are working, when families are doing more than just getting by.  And we both know it can be that way again."

Like Ryan, Romney also expressed concern about the challenges facing America's youth - particularly the unacceptably high rate of unemployment among young Americans.

"Every new college graduate thought they'd have a good job by now, a place of their own, and that they could start paying back some of their loans and build for the future," Romney sympathized.  "This was the hope and change America voted for."

Romney later asked Americans if they were truly content with the direction of the country over the last three years under President Barack Obama.

"Does [your America] fail to find the jobs that are needed for 23 million people and for half the kids graduating from college?" he inquired.

Romney was the final speaker at the week long convention that featured a wide array of voices in the Republican Party, including Sens. Rand Paul (R-Ky.) and Marco Rubio (R-Fla.).

He and Ryan are holding a goodbye rally at a nearby before heading to Richmond, Va. to campaign this afternoon.
