so now don't be so sad i have the answer for it. The best music player which i am using is called power AMP music player.
Best music player for android mobile that I am using
I am using it for my own Galaxy ace mobile. In Samsung Galaxy ace, it has a default music player and in this default player you wont get any features at all. but i am using power amp due to its various features and a lot of option for choosing to play music. The best features that i like to use in power amp players is sleep timer option. This will allow you to set sleep time for auto stop music. By the sleep timer you can choose the playing time and set the timer to stop music. Some time i like to listen music at night and at that time i use sleep timer for auto stop music after a certain period of playing. On the other hand if not it will continuously play and reduce battery power. So that's why for this case it give me a lot of ease of listen music. Some more i can change the tune settings according to music like rap, pop or solo music.
