Review: Motorola Droid 4 for Verizon Wireless
Music
The Droid 4 offers a lot of options for accessing and playing music. As far as apps go, there's MOG Music, Google Music, My Music, Slacker, and V CAST Tones. Those are all pre-installed.
The most useful of the included apps is Google Music, which acts as a local media player as well as a streaming music service. If you've uploaded your music to Google's servers, you can access it over the network from the Google Music app. It's a pretty good music player for the Droid 4.
Video
The Droid 4 has an abundance of options when it comes to accessing and playing video content, too. Preloaded apps include BlockBuster, NetFlix, NFL Mobile, Slingbox, Verizon Video, the stock Android video app, VideoSurf, and the stock YouTube application. Yeah, that's a lot. Oh, I forgot to mention that you can rent/buy movies directly from Google through the Android Market.
From this lot, I found the stock video and YouTube apps to be most useful. They are what you'll use to watch sideloaded content, content captured on the Droid 4 itself, and of course the social network through which you'll share your attempts at becoming the next Martin Scorcese. Almost all the other services will cost you extra money each month.
