Cash Money Records artist Kevin Rudolf had a hit last spring with a track that featured hip hop superstar Lil Wayne, but for Mashup Mondays, he chose to tackle the decidedly rocking tones of Lifehouse's "Halfway Gone," with just his own voice and an acoustic guitar.

"I love working on different kinds of music," says Rudolf enlisted Wayne on "Let It Rock" rose to No. 5 on the Hot 100 last May. "I chose [to do] 'Halfway Gone' because Jason Wade is such a great writer, great singer, and great artist."

The 2009 original track, which brings the full force of Lifehouse's guitars and drums to bear, peaked at No. 2 on Billboard's Hot AC chart.
