How to save songs on my iPhone through email?

I have a computer and I don't sync my iPhone to it. I emailed myself some songs. When I went to mail on my phone, it had the song and I clicked on the song. It just took me to another website so I can listen to it. How do I save it onto my iPhone?

The iPhone lets you open and listen to MP3s sent as email attachments, but not to save songs directly to the music app on your iPhone. To move songs that were sent as email attachments onto your iPhone, you must first download them on your computer and then sync via iTunes.
