I got the same messages, just a different phone number.  Glad I did some research before going to the site.

received the txt message (i don't have text messaging included in my package) from weRmp3.com.  fortunately i found this website, so i will know not to try to opt out.  thanks!

I too just got this spam text.  I found on this site
http://www.topix.net/forum/gadgets/ipod/TJ93J3SBMAN130612#lastPost what appears to be the customer service email address of this weRmp3.com site: support@wermp3.com.  Maybe if we flood their mailbox with angry emails they may think twice about their advertising campaign?
