It’s hard to believe it, but a quick check of the calendar shows that we’re almost halfway through the summer. Yes, already! On a related note, a quick check of the pop charts and our own Top 20 Video Countdown shows that Katy Perry‘s “California Gurls” has had a stranglehold on the top spot for the last few weeks, clearly cementing herself as the favorite to take home the this year’s Song of the Summer prize. However, don’t go engraving her name on the award just yet! Atlanta’s prodigal son, T.I., has been out of the clink and hard at work in the studio for a few months now and is ready to enter the race with “Got Your Back” (with a chorus featuring the sultry vocals of Keri Hilson). We’re excited to bring you a :30 sneak of the video here on the VH1 Blog today, and be sure to tune in to our Top 20 Video Countdown this weekend to see the whole thing. Let us know what you think in the comments!
