The Now Playing screen (which is always accessible from other parts of the app via slide-up bar at the bottom of the screen) offers a nifty Cover Flow-like view that showcases album art and gives you a peek at previous and next songs. You can also switch to a simpler list view if you prefer. Basic playback controls are at the bottom of the Now Playing screen along with a share button, which lets you post what you're listening to on Twitter or Facebook. Premium users can hit the graphic equalizer button to make granular adjustments to their sound quality.
If you find yourself wanting to venture outside of your personal music collection, DoubleTwist offers a couple of options. First, there's a built-in radio feature for streaming live stations from around the Web. All of the stations are organized by genre, but still, it can be difficult to navigate the seemingly endless nesting menus. Second, DoubleTwist offers a Podcast Directory, where you can search for and subscribe to some of your favorites. In the directory, I was able to find the podcasts I was searching for, but many users have reported differently. If you find that DoubleTwist is missing a podcast, you can contact the company directly to see if it can add it.
When it comes to syncing your music collection with your desktop computer, DoubleTwist is one of the best apps I've seen. In my tests, it was exceptionally reliable when syncing either via USB or Wi-Fi, though the latter method requires a premium upgrade. From the desktop computer, you can simply drag and drop content onto your mobile device and rest assured that DoubleTwist will do the rest. If your connection gets interrupted, syncing will pick up right where it left off. And if you mistakenly try to transfer a duplicate copy of a song over, the app won't make the mistake. Syncing to desktop collections is certainly where DoubleTwist shines, and it is reason enough to choose it over other Android music players.
