Despite being the archetype of heavy metal, Lemmy prefers 'Rock And Roll' to describe his band's genre. This is a backlash because he's displayed some disdain for this before. He is quoted as saying 'heavy metal was too slow and boring' at the time, and they wanted to play fast rock and roll as an antidote to it.
Lemmy has admitted that he has gotten sick of playing "Ace of Spades" at every concert, but he will continue to do so because he knows that the fans want to hear it.
The band made some poor business decisions earlier in their career with the result that many labels have released their own compilations featuring Motorhead tracks without being endorsed by the band.
Motörhead's first label, United Artists, had no expectations for the band, so they shelved the real first album (On Parole) and only released it after the band started to make name for themselves at Bronze Records.
After their stint at Bronze and GWR, Motörhead relocated to USA and signed to WTG (off-shoot of Epic Records). After releasing 1916, WTG gradually started to run themselves down intentionally and basically stopped promoting Motörhead and the band had to promote the next album (March or Die) themselves.
After WTG shut itself down, band went to the german ZYX records because they gave the best offer. Unfortunately, ZYX didn't want to put much effort to promote the band (beceause they claimed it would cost too much) and the album Bastards went unnoticed by the consumers.
Ozzy Osbourne, on "I Ain't No Nice Guy". It helps that Lemmy wrote the song "Hellraiser" for Ozzy, which was later done by Motörhead themselves on March Or Die.
Slash also appears in "Hellraiser" and does some solo work on "You Better Run".
No Export for You: Thanks to ZYX Records' incompetence, Bastards is rather hard to find.
Old Shame: Lemmy has expressed regret over appearing in the film The Decline of Western Civilization II: The Metal Years because he feels that the movie makes heavy metal fans and musicians look like idiots.
