Problem with text message, share music

[vaiolla]

My Question or Issue

Why, as my friends share music(from Android and Premium plan), I receive a text message with the content: "here is the song especially for you.... and link" but when I share music(I have an iPhone and Premium plan), in a text message only the link is sent without: "here is the song ...". I asked and they share in the same way I do. Why is that? Whoever knows?
