Review: LG Ally
Sadly, the Ally's music application is identical to that of most every other Android phone going all the way back to the T-Mobile G1. It works, but it doesn't offer much in the way of thrills. It's not too much of a pain to sort through your library and create playlists, but functionality is minimal and extras are non-existent.
As for loading music, it is easy enough to drag and drop your playlists to the media card via USB storage mode, but I am getting tired of this method. I update my library frequently, and scouring the contents of a microSD card to see what's on it is a pain in the rear. To that end, I've begun using DoubleTwist to manage iTunes integration with Android handsets. It's available as a free download on the Web.
Users can also choose to check out the Amazon MP3 store for purchasing tracks directly from the handset.
Despite the lack of a feature-rich music player, music playback does sound good through both the 3.5mm headset jack and via stereo Bluetooth speakers.
