I totally love them. My favorite of theirs is I'll Be Your Sister. People say they're punk, others say metal, and Lemmy considers them to be rock and roll. In my opinion, I think they're punk. Like they literally influenced many of the British hardcore punk bands that came after. Honestly, I get a bit of an 80's skate punk vibe from some of their songs. About their iconic frontman, he's awesome. Like the fact that he just wanted to play music to make others be happy and have a good time and not for money is based. Sometimes, I feel like they sound like AC/DC on speed.
Honorable mention:
I listened to the Shake Your Blood (sung by Lemmy) by David Grohl's side project Probot and it rocks! This is the kind of music I would've loved to hear from Motörhead, but unfortunately Lemmy passed away.
