8 Android music player apps
Shuttle offers lockscreen controls (Ice Cream Sandwich and above), notification controls, widgets, album and artist artwork downloads, and gestures support.
The devs behind the app boast that you can customize the experience in order to make it "your personal player". As noted in its name, the app also allows you to stream music directly from your cloud provider (DropBox, Box, SkyDrive, Google Drive), and also offers floating controls.
PowerAmp offers support for a diverse list of audio files, has a sophisticated equalizer, along with lyrics support and search, a number of widgets, and many others.
And yes, that does mean that features are scarce, so stay away if you're looking for very specific perks.
But it's also a lot more. For example, doubleTwist brings you free podcasts on a number of topics, allows you to sync your existing iTunes library seamlessly with your Android device, and has support for AirPlay.
Rocket allows you to customize its look with themes, supports streaming to Chromecast, can embed lyrics, and can be controlled through the lockscreen.
More likely, it's because of the extensive control you get over the sound that comes out of your smartphone. You've got sophisticated equalizer controls, bass booster, album art downloads, lyrics support, and widgets.
PlayerPro works with a number of plugins -- some will customize its theme, others will add widget support and a DSP pack. PlayerPro also automatically downloads album art, has support for lyrics, and offers lockscreen controls.
