Chris Davies from SlashGear is reporting that the new service from Slacker will offer access on demand to the company’s entire music catalog. The service will cost $9.99 per month, and includes all the services that are offered in the existing $3.99 per month Radio Plus service.

But for the extra money users get access to albums, individual tracks, top charts, station playlists and single artist radio stations. You can get all this via the web interface or the new apps released for Android, BlackBerry, and iOS Devices.

Users can create their own custom playlists that can be synced with your mobile device, so they can be played when you have no internet connection. This is a feature which is enjoyed by users of Spotify in Europe.

You get to choose from more than 8million tracks from the Slacker catalog, and carrier billing is supported via the apps if you are a customer of AT&T, T-Mobile or Verizon. You can get the applications free if you are already a user of Slacker Radio Plus but have less features.
