Sarah BuxtonSarah Buxton finally saw one of her dreams come true after five-plus years of waiting for her self-titled debut to hit stores this week. So it was even more rewarding for the singer when she learned that her single, 'Outside My Window,' has already sold 12,000 copies. That earns her the distinction of having the biggest opening-week digital single sales of a song from a debut CD by a female country artist in the history of Nielsen SoundScan, which tracks the numbers for digital downloads and CD sales.

Sarah celebrated the release with family and friends at a huge party in Nashville, and says that while she's excited to achieve such an accolade, she's learned after so much struggle to just take things one day at a time and enjoy the here and now, without looking too far ahead.

"I'm still in disbelief of the whole thing in general, so I haven't let the fact about my single sales really sink in yet," Sarah tells The Boot. "I've kind of learned to start being happy in the moment and live day to day, regardless of what success is, so I'm waiting, and maybe some day later I'll celebrate that. But I'm just kind of enjoying the moment right now and being here with everyone."

Sarah also reveals that she went out and bought her own CD at the store earlier in the day, and that her co-writer Luke Laird excitedly purchased two copies to support his friend.
