SAN ANTONIO -- Mobile phone users apparently spent 2007 urging people to "Party Like a Rockstar" and proclaiming "This Is Why I'm Hot."
San Antonio-based AT&T says the songs by Shop Boyz and Mims were its best-selling ringtones of the year. AT&T's the nation's largest wireless company.
AT&T offers 40,000 ringtones in genres ranging from pop to holiday music, but the most popular ringtones continue to be hip-hop, rock and pop.
Other top ringtones included "Crank That (Soulja Boy)" by Soulja Boy, Nickelbacks' "Rockstar" and Akon's "Don't Matter."
