Sheryl Crow called U.S. Rep. Sue Myrick "a rock star."

At a congressional hearing Wednesday, the pop-rock singer praised the Charlotte Republican's efforts to draw more funding for the environmental causes of breast cancer, the Charlotte Observer reports.

"I want to know what causes this disease," Crow said in testimony before the House Energy and Commerce Committee's health subcommittee. "We need to put more resources into figuring out what the environment has to do with breast cancer." 

Myrick is not the only one Crow has praised that way, though it was unusual for a well-known liberal to praise a Republican. In an interview with People magazine, she also called her son, Wyatt, a "rock star."

Dome would like to note that Crow herself is not actually a "rock" star. Soft rock star, maybe.

Sheryl Crow may be having her moment in New Hampshire.

According to Dome correspondent Mark Johnson, her 1996 song "A Change Would Do You Good" has showed up already on the pre-rally songlists of John Edwards and Hillary Clinton.

As far as music goes, Crow is a safe choice for mainstream rock, though the lyrics to this song are not as PG-rated as you may have thought.

Among Democrats, she's also a good pick, known for raising awareness of global warming with Laurie David. (And equally derided in other quarters for famously suggesting a ban on using too much toilet paper.)

Still, there are other choices out there if "change" is the message. For the smart set, there's David Bowie's "Changes." There's the classic civil-rights anthem "A Change is Gonna Come" by Sam Cooke (or Aretha Franklin's more personal version, which might suit Edwards better with its "born by the river in a little tent" vibe.). 

And, of course, there's "Turn! Turn! Turn!" by the Byrds, although that may be too boomer-centric for anyone but Hillary Clinton.
