 A month after launch, Twitter #Music is certainly not setting the world on fire, In fact ,as of yesterday it had fallen out of the top 100 free music apps. They are, however, already iterating to improve the offering. Today, Twitter added charts that look very similar to those previously found on WeAreHunted, the innovative music discovery startup that Twitter acquired to power much of #Music.

Users can toggle through 10 genres and examine #Music activity on artists categorized as Supertsars, Popular, Emerging, Unearthed and Hunted. There are also tabs for Suggested (“music you might like”), #NowPlaying (“Tweeted by people you follow”) and Me (“arists you follow”).

Rdio and Spotify users can play full tracks from the chart after sign-in.

#Music Charts is not yet available on the iOS app, but is viewable on the web now.
