Spotify has launched another great update for its iPhone edition.

After recently acquiring EchoNest and releasing a fresh update that allows you to find new music even while you’re offline. Now, Spotify, the popular music streaming app now allows you to view your playlist’s queue and even notifies you if you you add a new song that already exists on your playlist.

If you do try to add an existing song then you’ll be prompted to abort your action or go ahead with it despite the pre-existing song in your playlist.

Moreover, you can even sort and filter your song selection on personal preference.
