Usually, when FMQB lists music for a certain date [such as 3.30.10] then to be honest, in the radio world... It's supposed to make an "impact" by the 30th, now having said all of that radio stations should get the single on the 22nd-23rd, the larger markets/cities may even see the track next week. Not that I want a leak, but this just has "early leak" written all over it. Usually iTunes/Amazon are good for tracks on the their debut days, so keep an eye out for that. Either way, I never thought I'd once be talking about Stone Temple Pilots, Pearl Jam, Soundgarden, and Alice In Chains in 2010... This is an incredible time for us rock fans.
