10/6 Update: After Adele's "Skyfall" was released Thursday evening (Oct. 4), the song is already trending around the No. 30 rank on the building all-format Nielsen BDS-based Radio Songs chart (which runs from Wednesday through Tuesday each week). So far, it's garnered 21 million audience impressions. As for genre airplay charts (which run from Monday to Sunday), "Skyfall" is already No. 16 on the building Adult Contemporary chart (with slightly more than 200 plays so far), No. 33 on Adult Pop Songs with (morethan 300) and No. 37 on Pop Songs (about 700).
"Skyfall" is selling big digitally, as it's been the No. 1 song in the iTunes Store since shortly after its release on Thursday night. Label sources suggest it sold twice as many downloads on Friday (across all retailers) as it did the day previous. That said, "Skyfall" may move between 200,000 and 250,000 downloads by the end of the SoundScan sales tracking week on Sunday, Oct. 7. That's a mighty number for being on sale less than four full days. As we said on Friday, however, predicting "Skyfall's" sales is difficult, as traditional sales projection models can't necessarily be used for mid-week releases.
At the rate "Skyfall" is selling, it should debut in the top four on the Digital Songs chart this coming Wednesday (10), possibly with One Direction's "Live While We're Young," Taylor Swift's "Red" and PSY's "Gangnam Style" likely at Nos. 1-3, respectively.
