After the first 24 hours, Spotify played 11,984 songs compared to the 11,612 that played over iTunes and the 3,457 that came from Rdio. Overall, 256,226 tweets went out under the hashtag #NowPlaying in the first 24 hours. That was four times the number of Vine posts that went out in the video snippet app's first 24 hours. On the other hand, Vine does not offer its service over the web like Twitter #Music does.
With its new service,Twitter has its finger on the pulse of the music industry, knowing what's hot and trendy and which songs are receiving "tweetplay" (to coin a new word). Information like this, in real time as it is, can be worth mucho dineros to the record labels. Hear that sound? It's the sound of Twitter monetizing its data.
