i think you have missed single quote link like operator

 Cursor c = myDB.query(MY_DATABASE_TABLE, "songname","songname like '%"+MATCH_STR+"%'" , null, null,"SongHit", null);

check and correct your query

try below code for search :-

public Cursor getROUTINENAME(String search_str) {
        String query = "SELECT * FROM TBNAME where COL_NAME LIKE '%"+search_str+"%'";

        Cursor mCursor = db.rawQuery(query, null);
        if (mCursor != null) {
            mCursor.moveToFirst();
        }
        return mCursor;
    }

call above function with string .
