Freestyle Rap game ideas

[Premmy]

Idea 1:
the Game host posts a beat, two people step up and face off in a traditional MC freestyle. the winner decides the next beat and someone steps up to dethrone him/her

Idea 2: The first person selects a beat for the thread, posts it. He then Decides on a theme for the first rhyme, puts it forward and rhymes for however long he can go with it, then chooses the theme for the next player
kinda like this (http://www.youtube.com/watch?v=C5PElv46G1E)
Edit:
to clarify, the first verse had "Take" as it's theme the second "Hold", the third "fire". The lyrics typed or spoken here would sound like that song all played together

Yes, i would totally be down with that, whichever people choose!

[Fifthfiend]

Yes, do either of these, approved, go.

[Funka Genocide]

dude, I will destroy everyone in this game.

maybe.

I'm actually sort of interested in seeing how this shapes up though.

I haven't rapped since aught-two.

okay time to clean up some details,
you can enter with either text, sound or video, don't care, as far as video goes NSFW rules from the rest of the forum apply.
Beats: The actual beats for either competition can either be offered by the various competitors and I'll choose the best ones and arrange them in a list, or I can pull from my collecton of instrumentals from my favorite artists: MF DOOM Madlib Jaydilla Aesop Rock, Oh No e.t.c. decide before we get started.
Battle: a Battle has to be officially announced, meaning any damn body can't just jump up, they have to challenge, I have to approve, then you two can start. This is mostly for the sake of organization so we don't get fifty people at once in one battle,
Themed Rhyming: once you finish your verse for the previous theme, you have to go out on the word of the theme you choose for the next person, I.e. if you were to choose "Take" as your theme the last thing you should say/type should be "take". Themes should be common improper Nouns Adjectives and verbs, nothing too complex to make this easier for everyone.

Judging:..... any ideas? me as the sole judge? panel?, voting? up to ideas.

Edit: Honestly, when it comes to beats, the best and only(as of now) one I can think of for the Themed rhyming game is DOOM's Change the beat, (http://www.youtube.com/watch?v=jEyg6RKtvTI) it's just varied enough to accomodate anyone's style, and well, it's awesome.
