"Oogachaka!"



Sales of Blue Swede's "Hooked On a Feeling" have gone through the roof following its use in the new trailer for the film "Guardians of the Galaxy."



According to industry sources, the song sold more than 2,000 downloads on Wednesday (Feb. 19) -- up about 700% in daily sales. The two-and-a-half-minute trailer bowed Tuesday (Feb. 18) on ABC's "Jimmy Kimmel Live" at 11:35 p.m. ET.



Sources say that the song's 2,000 in digital sales instantly gave the tune its best digital sales week ever. (And again, that's after just one day of sales.) The current sales tracking week ends on Sunday, Feb. 23. We'll have the official weekly sales of the track, collected by Nielsen SoundScan, next Wednesday, Feb. 26.



In the week ending Feb. 16, the song sold a negligible figure.



In the trailer for "Guardians of the Galaxy," the familiar "oogachaka!" chant from the song can be heard at around the 1:30 mark, and is then repeated during a montage of fiery action scenes. The song is then heard without interruption for the last 20 seconds of the trailer.



The song's previous best digital week came in 2008, when it sold 1,000 downloads (in the week ending March 16).



"Guardians of the Galaxy," starring Chris Pratt and Zoe Saldana, will be released in theaters on Aug. 1.



Blue Swede's "Feeling" became a No. 1 Billboard Hot 100 hit for the Swedish band, reaching the top on the chart dated April 6, 1974. It was one of four Hot 100 hits for the act, which also charted a top 10 single with "Never My Love" (No. 7) in October 1974.



Blue Swede's take on "Feeling" is one of three visits to the chart for the song, which was first a hit for B.J. Thomas in 1968. He took the song to No. 5 on the Hot 100 in early 1969. Decades later, in 1998, thanks in part to the TV show "Ally McBeal," the song returned to the chart. A dancing baby -- grooving to Blue Swede's "Feeling" -- appeared as a hallucination on the show in January 1998. Known as "Baby Cha Cha," the animated infant was already a viral sensation by that point, but its popularity hit a new level after its use in "Ally McBeal."



That popularization -- along with Baby Cha Cha's subsequent appearances in assorted TV commercials -- led to a new recording and commercial CD release of the song, credited to the anonymous studio group Baby Talk. The single went on to sell 111,000 copies, according to Nielsen SoundScan, helping it reach No. 71 on the Hot 100 the week of June 6, 1998.
