Actress Shraddha Kapoor’s soothing voice in songs like Galliyan and the recent Bezubaan Phir Se has been well appreciated by listeners and now she hopes to please talented musical trio Shankar-Ehsaan-Loy with her singing skills in Rock On 2.“I just enjoy singing and I’m not professionally trained. But I just love singing. And I’m hoping that with these classes my singing improves further,” Shraddha, who is undergoing voice modulation classes to fine-tune her voice for the film, said at the cover launch of Hello magazine starring her.
