Ever watch Katy Perry's "California Dreams" video and just want to jump on that trampoline with her? Or, have you ever wanted to walk around in that fancy military jacket worn by Coldplay's Chris Martin? Oh, and you fashion fans, how about owning Jane Birkin's original Birkin Bag as designed for her by Hermes?

I bet you do, and now there's a way to buy all of these and help earthquake and tsunami-ravaged Japan via the EMI music groups exclusive online charity auction.

Located here, the auction also offers up exclusive items from 30 Seconds To Mars, Gorillaz, Norah Jones, The Beach Boys, David Guetta, Keith Urban and Lady Antebellum.

And, better yet, EMI Group has committed to match all funds raised from the auction up to a maximum of one million euros.The first phase (which includes the Birkin and Martin's jacket from the 2010 Viva La Vida world tour, plus the Beastie Boys' Japanese MTV Award) will run until April 15th, while a second phase of the auction will take place between April 11th – 21st.

Norah Jones tells UsMagazine.com: "Japan has been one of my favorite countries to visit and my heart goes out to everyone affected by this disaster. I'm so glad I can be part of this fundraising effort along with the EMI family. It helps make things a little bit easier at such a difficult time."
