PERRY POWER

Hey Gary!

I've spent the last week or so trying to track down up-to-date sales for all of Katy Perry's singles. Any information you can give will be much appreciated!

Thanks,

Hi Scott,

Here is a ranking of Perry's top 10 most-downloaded songs, release-to-date, according to SoundScan:

4.908,000, "Hot N Cold"
4,862,000, "California Gurls"
4,488,000, "Firework"
4,063,000, "I Kissed a Girl"
3,940,000, "E.T."
3,747,000, "Teenage Dream"
1,994,000, "Waking Up in Vegas"
928,000, "Thinking of You"
882,000, "If We Ever Meet Again" (Timabaland featuring Katy Perry)
401,000, "Last Friday Night (T.G.I.F.)"

Expect "Friday" to quickly and sharply roar up this list, as the song is currently No. 1 on the iTunes store's ranking. It should blast from No. 31 into the Hot 100's upper reaches next week, as its eight-minute video - sporting cameos from Rebecca Black, Darren Criss, Corey Feldman, Kenny G, Debbie Gibson and others - has racked 15.6 million YouTube views in less than a week since its posting.

As for your location, the Bruins' winning the Stanley Cup Wednesday (June 15) for the first time since 1972 may personally outrank the Red Sox' 2004 World Series win (after the team's 86-year title drought) as my favorite sports fan experience, having gone to so many Bruins' games with my father, who covered the team for several years for the Patriot Ledger, and brother since 1983.

(Finally, my brother can no longer taunt that the Bruins have won two Cups in his lifetime (1970, '72) and none since I was born in '74 ...)

In honor of the newly-crowned champions, an audio toast to the team with the song that serves as the soundtrack to each Bruins home-ice goal at Boston's TD Garden, Zombie Nation's "Kernkraft 400":

See you at tomorrow's parade! (As a Facebook friend joked, "I'll be the one in the Bruins shirt and hat!")
