I found it very dull and not unique at all.
So I got an idea.... XBL could sell a short 30 second ot 60 second clip of songs that you can add to you're profile... so that when another user opens you're gamercard they will hear the song that you chose.
This could bring xbox tons of cash... They could easily sell for 150 Microsoft points per song, or more for new songs.
This can even be sold at the "avatar store" when ever that opens.
I know that I would love to see this, how about you?
