This paper proposes to use the core vocabulary of English grade test as the basic unit and keywords and find English songs containing these vocabularies through data search, so as to establish the test-oriented English song database and develop the corresponding APP. The contributions of the paper contains the following two points: (1)This APP has great practical effect and fills the English learning gap in the existing mobile phone application market, because most of the existing Apps about English learning focus on memorizing vocabulary and do not pay attention to the cultivation of students’ comprehensive communicative competence.
(2)It has social benefit and commercial value. Our main research object is to improve the ability of students without English major to pass the Band 4 and 6 College English Test. However, it is widely used for various language level examinations, such as Band 4 and 8 English Test for students with English major, IELTS, TOEFL, and other foreign language examinations. All in all, the establishment of the test-oriented English song database and the development of its corresponding APP have practical value. Its existence not only conforms to the scientific law of second language acquisition, but also fills the blank of the application market, and can bring good social benefit and commercial value.
