PocketLast.fm really is a minimal version of the full Last.fm social music service. As such there’s no facility to “love” or “hate” a song – there are only options to select tags for music genre search and alter the volume.
The interface displays the artist, song title and album cover as you would expect, but beyond requiring you to sign in to your Last.fm account, this is as sophisticated as the application gets.
International considerations may vary – however when using the application on the GSM band in the UK, it fails with a non-specific and pretty unhelpful error message that can only refer to the type of internet connection currently active. Running over WiFi, 3G and HDSPA works fine, however.
Note that a generous dataplan should be running on your network contract before installing and using any software that can result in high peak tariff charges for data use.
