Obama's iPod: Dylan, Stones and Lil Wayne

President Barack Obama's taste in music still tilts toward the classics of his childhood. But with the help of his younger aides - and his daughters - the president says his collection is becoming a bit more hip.

In an interview with Rolling Stone magazine, Mr. Obama says his iPod has about 2,000 songs, including ones by Stevie Wonder, Bob Dylan and the Rolling Stones. The president's personal aide Reggie Love has improved Mr. Obama's rap repertoire, introducing him to artists like Nas and Lil Wayne.

Mr. Obama also says his daughters, 12-year-old Malia and 9-year-old Sasha, are getting old enough to start sharing their taste in music with their dad.

The president says music is a great source of joy and solace in the midst of difficult days.

The interview also touched on more serious topics, like the perceived enthusiasm gap between Democratic and Republican voters ahead of November's midterm elections.

Admonishing his own party, Mr. Obama said it would be "inexcusable" and "irresponsible" for unenthusiastic Democratic voters to sit out the midterm elections, warning that the consequences could be a squandered agenda for years.

"People need to shake off this lethargy. People need to buck up," Mr. Obama told Rolling Stone. The president told Democrats that making change happen is hard and "if people now want to take their ball and go home, that tells me folks weren't serious in the first place."
