自己做了一个相对完整的音乐播放器，现在把播放模块提取出来，分享给大家。音乐播放器基本功能都实现了的，可能有些BUG，希望谅解。

播放器功能如下：
1.暂停，播放
2.拖动条实现，快进，快退
3.歌词同步
4.下一曲，上一曲。
5.专辑图片显示
6.后台播放，通知栏显示
7.来电话，暂停，电话结束，开始播放。(I made a relatively complete music player, now the player module extracted, to share with you. Music player basic functions have been realized, there may be some BUG, I hope understanding.

The function of the player is as follows:
1. pause, play
2. drag strip, fast forward, rewind
3. lyrics sync
4., the next song, the last song.
5. album pictures show
6. background playback, notification bar display
7. calls, pause, phone ends, start playing.)
