What LP said.
Although I would reccommend the 2 disc The Best of Motorhead instead, for three reasons.
1. It's a more complete Motorhead retrospective since it goes up to 2000, where the other is till 1984ish i believe.
2. It has their cover of "Louie Louie" on it, as well as Lemmy's old band Hawkwind's song "Motorhead" and Lemmy's sideproject Headgirl playing "Bomber" and "Emergency".
3. It comes with extensive liner notes that make the booklet a great read. Much to learn is presented within it.
I love Motorhead to death, but I really don't pick up all their albums because they do all sound the same. That's only reccommended for the Lemmy-obsessive.
