Having taken the streaming music business by storm with its Mac and PC applications, Spotify Mobile has now arrived for the iPhone.
Spotify Mobile is free, but you can only use it if you have a Premium Spotify account. There is no ad-supported mobile version. However, with an account you have a really impressive application. Wherever you are you can listen to anything from Spotify's huge and expanding library. You can sync with playlists you have on your desktop, create new ones, or just listen to albums, or artist selections.
The Spotify Mobile interface is really slick and intuitive. Searching is easy, while results are easy to browse and well organized. Any track you listen to can easily be added to playlists, which themselves are easy to edit, reorder and shuffle.
There is support for offline listening too, although obviously you can't use saved music in any other app. Another limiting factor is when streaming using your 3G connection, Spotify Mobile will eat away your battery!
Despite these small issues, the Spotify Mobile app is quite an achievement, and if you have an account and an iPhone, downloading it is a no brainer! If you don't have a Spotify premium account, this might be the app that changes your mind.
Listen to almost anything you like, whenever you feel like it. Spotify Mobile is a powerful and really intuitive music application for your iPhone.
