Invisible by U2

"Invisible" is a song by Irish rock band U2. Unveiled in a Super Bowl XLVIII television advertisement, it was available as a free digital download through the iTunes Store from 2–3 February 2014. Bank of America gave $1 for each download of the track to (RED), an organisation co-founded by Bono, to fight AIDS. Since 4 February, it has been available as a paid download, with all the proceeds also going to (RED). The song was later included as a hidden track on the deluxe edition of the group's 2014 studio album Songs of Innocence. The electronic-tinged rock anthem was met with generally favourable reviews from music critics. The song has also charted in several countries, and topped the Billboard Adult Alternative Songs chart in the United States. A music video for the song was directed by Mark Romanek and released on 11 February 2014.
