Billboard and Twitter have integrated a Bop.fm music player into select charts to allow online users to hear each charted tune. At launch, Bop.fm play buttons have been added to the Twitter driven Trending 140, Last 24 Hours, and Emerging Artists "real time" charts on Billboard.com.
"The Hot 100 itself is not going to have everything available on Spotify or Rdio at all times (such as Taylor Swift, Beyonce, latest Drake cuts, etc). For the Real Time charts, that is even more prevalent," bop.fm co-founder Shehzad Daredia told Hypebot. "And even if a piece of content is available on Spotify, that would mean only a small fraction of their audience would be able to play it back. The digital music world is too fragmented to allow only one source of music playback on a broad-reaching web property.
Bop.fm is "service-agnostic" pulling music from YouTube, SoundCloud, Rdio, Spotify and other services.
