Remember Def Jam Rapstar? The SingStar for...rap? It had promise, but ultimately fizzled on the vine and died without making much of a splash. Now, making things worse, a record company is trying to squeeze the game's creators for millions.

Def Jam Rapstar, the hip hop karaoke title from 4mm Games, will be out on October 5 for the 360, PS3 and Wii. And it'll live and die on the strength of its tracklist, which at the moment, looks...decent!

It's easy for us, as jaded gamers, to dismiss 4mm Games' Def Jam: Rapstar as a Johnny Come Lately. Thing is, the game isn't for us.

4mm's Rapstar intrigued me at E3, but music games live and die by their tracklists, not their good intentions. And neither of these new "trailers" for the game give any hints whatsoever.

With his likeness plastered all over Beaterator, rapper and producer Timbaland is definitely serious about the PSP title - serious enough to use it on tracks from his upcoming album Shock Value 2.

Like all music games, 4mm's Rapstar will live and die on the strength of its tracklist. Convenient topic, that, since we've got hold of the names of seven of the game's tracks.

While other members of Team Kotaku are busy flying/driving home today, I had one last E3 appointment to attend: spend some time with 4mm Game's hip-hop karaoke title Rapstar.

4mm Games - the new studio formed by the two of the guys who founded Rockstar - have announced their debut game. And it's called Def Jam Rapstar, a hip-hop karaoke game.
