Sugarland, Taylor Swift, Carrie Underwood are among the artists donating valuable items and memorabilia -- including face time with the stars -- to raise money for MusiCare's Back to School Charity Auction.

Sugarland, Taylor Swift and Keith Urban join Jennifer Hudson, Ke$ha, Dr. Oz, Guy Fieri and Smokey Robinson in offering a meet-and-greet with the winning bidder. Lady Antebellum, Kenny Chesney, Carrie, Paramore, Justin Bieber, Blake Shelton, Miranda Lambert and Zac Efron are all donating signed memorabilia, including guitars and posters.

Other big ticket items include spending a day with President Bill Clinton, working out with Oscar winner Gwyneth Paltrow and a private lunch with 'Glee' star Matthew Morrison.

This isn't the first time country stars have made generous donations for the Grammy-based organization. Lady A and Keith Urban are a few of the country superstars who previously donated autographed items to the Red Cross earlier this year, with all the proceeds going towards Japanese relief following the country's devastating earthquake and tsunami earlier this year.

The auction, which runs through Friday, July 29, can be found here. Proceeds benefit the Grammy foundation's Grammy in the Schools programs, as well as their healthcare and addiction recovery programs.
