Okay seriously, is Rammstein a Nazi band or not?

Let's settle this once and for all!!! This issue is way too damn controversial. Are they nazis or not??? On various websites I keep seeing people who are saying that Rammstein's songs have nazi undertones to them, and that Rammstein is lying when they say they're not nazis. This is very frustrating and confusing to me, and I don't know who to believe. If they are truly a nazi band I will stop listening to them. So folks, are they or are they not?? I personally don't think so due to many reasons.
