Before this update, SoundHound already had tie-ups with several streaming platforms, including a similar automatic playlist feature via Spotify. This particular Rdio news, though, is similar to an announcement made by Shazam in July. The rival company said it would offer automated Rdio playlists in addition to full-song streaming from Rdio within its own app. SoundHound and Shazam have long been nipping at each other’s heels to secure dominance in the music identification field. It’s no surprise that both are rolling out similar features in an effort to land on top, but it does raise the question of how either company will to stand out, especially now that the initial divide between connected streaming services has disappeared.
