ABC is continuing its emphasis on free music as a promotional platform. Starting Sunday, a gratis download of the “episodic score” in drama “Once Upon a Time” became available on ABC.com for 24 hours.

That followed a free download opportunity for the tune “Hold On” by Alabama Shakes used Wednesday in “Revenge.” Both became available on ABC.com’s “music lounge,” which has a 24/7 streaming radio station with songs from ABC hits from “Dancing with the Stars” to “Desperate Housewives.” 

The music lounge also is offering an interview with Mark Isham, who composed the “Once Upon A Time” score, speaking about the show’s music inspiration.

The “music lounge” microsite was launched in May 2009, offering frequent music downloads, artist information about ABC prime-time series, music videos and the radio network.

Viewers can also buy the music. This week, Lady Antebellum tunes featured on “Dancing With the Stars” and “Jimmy Kimmel Live” are being promoted.  

ABC has used the music lounge as part of a campaign plugging its involvement with the Lilith Tour, a music event raising money for women’s causes.

ABC aired the “American Music Awards” Nov. 20, and Sprint allowed people who voted online for best new artist to get a free download at the music lounge.
