To get the jump on Plants vs. Zombies, Popcap's next game, you can go here to sign up for a 10% discount and an early download before the May 5th release. But perhaps more importantly, you can dig on their weird little music video (pictured) and even download an MP3 of Laura Shigihara's song, with your choice of English or Japanese lyrics.

Miss Shigihara explains on her blog how the song came about:

...about two months ago, after finishing all the in-game music and SFX, I decided that I wanted to make a funny theme song... I thought it would be awesome if the song was basically a dialogue between the Sunflower and the Zombies...A couple weeks ago, the marketing team suggested we make a Japanese version as well, and being that I'm half Japanese, I decided I should represent. So I translated the lyrics, and got help from my Dad to refine them... originally I was going to leave the Zombie lyrics (sung by George) in English. But as I was going through the Japanese lyrics, I started mumbling them in angry-zealous Japanese and thought, "this is really funny... I bet my Dad could do this." So he came over and we recorded that while my mom played Twilight Princess downstairs...

In terms of how Plants vs. Zombies will play, Popcap is still mostly mum. This is apparently a tower defense game with elements of card collecting. But most importantly, it's from the folks who made Bejeweled and Peggle. If they're not capable of building a delightful tongue-in-cheek time-waster about a singing sunflower fending off a zombie siege, no one is.
