I'm using Rocket Music Player. It has all the features and option you asked in your question like
Forward-Rewind(Track bar control),
You can even access the player's
Go to Album,
Go to Artist,
Add to Playlist,
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 > Operation > Lock Options > 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!!!
