U2's new song "Invisible" has been anything but on the radio.
According to Billboard, the tune, available as a free download via iTunes through 11:59 p.m. Feb. 3, enters the Rock Airplay chart at No. 35, the chart's biggest gainer, after one day of airplay, with 2.2 million "audience impressions" from plays at 50 rock airplay stations.
Also, according to radio industry sources:
* As of about 3 p.m., "Invisible" had been played at least once on almost five dozen radio stations in the U.S.
* More than 20 stations had already played the song 10 or more times.
* It’s had the most “spins” on Alternative (148), Active Rock (97) and Rock (89) stations.
Because the song has been available as a free download -- with Bank of America donating $$1 for every download to the (RED) campaign -- the release won't show up on the standard singles charts, which are based on sales.
According to Gary Trust, charts manager at Billboard, the company does "not include giveaways on our charts as part of our minimum pricing policy." He added that "iTunes' free downloads are not reported to Nielsen SoundScan, which provides the data for our charts," so those downloads do not affect Billboard sales charts anyway.
