About 40 seconds of the dance-meets-acoustic track materialized with Madonna singing, "I've spent some time as a narcissist, hearing the others say 'look at you, look at you.' Trying to be so provocative, I said, 'Oh yeah, that was me. All the things I did just to be seen.'"
It's assumed the song is titled "Rebel Heart," as Madonna is heard singing the phrase at one point in the snippet, and because she used the #RebelHeart hashtag on her Instagram for months. The song might be a co-production with Avicii, as Madonna used the #RebelHeart hashtag in a photo of her with him and his team nine months ago.
It's unknown if the song clip is from a demo version of the song or a recording of a finished track. (As the audio quality of the snippet is questionable -- it sounds like it was recorded through speakers -- some observers have suggested the song is unfinished.)
Madonna has been working on new music throughout 2014, frequently updating her Instagram feed with photos and messages regarding her progress. A new album from the entertainer is expected in 2015. It will be her first studio effort since 2012's MDNA, which debuted at No. 1 on the Billboard 200 chart.
