You can get all the mp3 files from rooted sdcard by the following code.

File home = Environment.getExternalStorageDirectory();

if (home.listFiles( new Mp3Filter()).length > 0) {
    for (File file : home.listFiles( new Mp3Filter())) {
        songs.add(file.getAbsolutePath());
    }
    ArrayAdapter<String> songList = new ArrayAdapter<String>
          (this,R.layout.song_item,songs);
    setListAdapter(songList);
}

class Mp3Filter implements FilenameFilter 
{
    public boolean accept(File dir, String name) 
    {
        return (name.endsWith(".mp3"));
    }
}

Here songs is a ArrayList which stores the actual path of the song.

Use FileFilter for scanning the .mp3 files from sdcard. like:

 //Check media mounted or not
  if(Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()))
{
File sdCardDir=new File("/sdcard");
File sdCardDir=Environment.getExternalStorageDirectory();
ArrayList<File>files=getFiles(file);
private ArrayList<File> getFiles(Filefile){
File files[]=sdCardDir.listFiles(filter);
for(File f:files){
if(f.isDirectory()&&f.canRead()){
    getFiles(f);
}else if(f.isFile()){
   videlList.add(f);
}
}
//USE FileFilter 
FileFilter filter=new FileFilter(){
@Override
public boolean accept(File f){
returnf.isDirectory()||f.getName().matches("^.*?//.(mp3)$");
}
}
