I couldn’t tell you who was at the top of the hit parade now if my life depended on it. Then again I’m an old man, as you can tell from my use of the phrase “hit parade”. But if you’re young, or hip it would be great to have the UK’s most popular tracks in your pocket at all times wouldn’t it? O2 seem to think so and have released O2 Tracks, which brings the Official UK Top 40 Singles Chart direct to your phone, wherever you are and whenever you want it.

The app makes chart tracks, as well as a changing selection of curated playlists, available. The tracks available in the app are updated weekly – with new entrants replacing songs that have drifted out of the Official UK Top 40 Singles. However, if you want to buy a track to keep you can directly from the app.

Customers on O2 get a two month free trial and then pay £1 a week directly onto their bill for O2 Tracks while those on other UK networks have a two week trial and then £4.99 a month.

Out now for Apple, Android, BlackBerry and Windows Phone.
