A better music control on lock screen I am new to the android world, used to be an iphone user.
I would like to know how can I get a better music control player on my lock screen?
Is there anyway to add more options, like the trackbar to move forward within the song, repeat and random buttons etc?

thanks
I'm using Rocket Music Player. It has all the features and option you asked in your question like Prev, Next, Random, Forward-Rewind(Track bar control), Repeat. 

Additional Options:

You can even access the player's Playlist, Go to Album, Go to Artist, Add to Playlist, Delete, Ringtone from the lock screen itself by clicking the three dots at the bottom right of the display. 

For this to appear in your lock screen you need to, Install Rocket Player and open the music player's and go-to

Settings &gt; Operation &gt; Lock Options &gt; Rocket Player.

Take a look at the screenshots for enabling this,

To unlock the screen you need to just swipe the Blue Arrow to the right side blue dot.

Hope its useful. Enjoy Music!!!
