Changing musical ring on cell phone during Sefirat Ha-Omer

Q: Is it necessary to change a musical ring of a cell phone during the period of Sefirat Ha-Omer?
A: There are two sides to this question: 1. The one who owns the cell phone should ideally change to a ring without music. In the book "Doleh U-Mashkeh" (p. 193), Rav Chaim Kanievsky answers this question that it is best to be careful and change it. If he does not change it, however, it is not an eternal tragedy since it is only a few seconds of music. Furthermore, this is not exactly music, it is a short snipet. 2. If you call and you receive a musical ring, it is called a "benefit which comes to a person against his will" (Pesachim 25).
