'One Tree Hill' actress Jana Kramer blew country radio away this week with the release of her debut single, 'Why Ya Wanna.' The tune was added to the playlists of more than 55 radio stations across the country, the most of a debut artist since the inception of the Country Aircheck/Mediabase chart.

"'Why Ya Wanna' is a song that everyone can relate to," Jana explains. "When I first heard the song, I was hooked immediately. It was literally everything I was going through and more, so it meant a lot to record a personal song that became my first single."

In addition, Jana nearly tripled the previous record for any debut female artist, according to her label, Warner Music Nashville. "I have to thank country radio for believing in me," says the brunette beauty. "I'm beyond humbled and excited for this amazing start to my music career."

'Why Ya Wanna' isn't just impressing at radio, the song has already been downloaded nearly 200,000 times to date. It will be included on her upcoming debut album, which will be released later this year.

All of which must be putting any fears Jana had of breaking into the music industry to rest. "People say, 'Oh, she's just an actress trying to be a musician,'" Jana lamented to The Boot last summer. "And I say, 'No, I'm serious about this. I bought a house in Nashville! I moved here before I even got a record deal. I just had the mindset of, 'I'm here, whether it takes me three years or three months.'"

In fact, Jana is trading in the small screen for the recording studio. Her very last 'One Tree Hill' episode airs tonight (Jan. 18).

Jana is currently in the studio with producer Scott Hendricks (Blake Shelton, Brooks & Dunn) putting the finishing touches on her full album. Listen to 'Why Ya Wanna' here.
