Z's chart update

As I wasn't here last week, I thought I'd just tell you what to expect in this week's chart, as I missed last week's :P
So California Gurls may be making its way onto the top spot, unless Love the Way You Lie can hold it off. Meanwhile, expect a very high entry from Diana Vickers with the Boy Who Murdered Love. Expect Pack Up and Just Be Good to Green to go up, and expect some re-entries due to Now 76, and maybe some old songs entering this week's chart as I have been listening to some goood old songs on my mp3 player over the last few days while I was away.
