The exclusive Samsung Galaxy app will offer users unlimited playback of the UK's hottest tracks.
Samsung has already thrown itself into the mosh pit of mobile music streaming with the Music Hub, and it's continuing the rock star movement with the launch of The Official Top 40 Chart app.
White label mobile music solutions firm MusicQubed powers the app, which is an exclusive to Samsung's Galaxy smartphones. It will debut on the Ace II.
Users will be treated to unlimited streaming for all 40 of the songs found in the charts, as compiled by the Official Charts Company.
The memory is cached when the app isn't in use, eliminating the buffering process, while the chart is updated daily to provide the latest playlists.
A celebrity news update feature can be found on the platform too, while social network connectivity allows listeners to share and comment on their latest musical choices.
The app is free for the first two months, and the 'Access All Areas' pass will cost £1 per week after that.
