Seriously if you like music for ideologies and aesthetics you're going through the wrong medium. Read a book and attend fashion shows.
Glad to see the old av back hubster
I kinda disagree with this to a certain extent. You're right that hating a band's music but still listening to them because they fit in nicely with your ideologies and possibly your general "style" as an extension of said ideologies is kinda retarded. I often imagine confused skinheads being played Burzum by other confused skinheads and pretending to enjoy it but not really having a clue what's really going on. On the other hand, I don't think it's detrimental to be attracted to or interested in a band because of what they preach.
I totally dig all the Negura Bunget-esque love for nature etc., which is actually why I first started listening to the band, and partially why I'm such an avid fan. If they had written the same albums but were rabid right-wing nationalists, I definitely wouldn't be so enthusiastic about and supportive of them. (I realise there were some rumours about some of the original lineup having racist affiliations but I hardly feel that is evident through their music, lyrics or professed ideologies). I also thoroughly enjoy hearing a new band and digging their stuff, then doing a little research into their beliefs and lyrics and recognising how these things manifest themselves in the songs. This obviously can't be applied to all music though ahah, as some dudes are just out to make a heavy tune and that's the end of it.
I suppose to really address your issue I'd have to say whether or not I like certain music BECAUSE of the ideologies of the band, but I think it's kind of hard to separate out. For example, I believe I like Agalloch because Agalloch think about similar things to me when they craft their music, so I am bound to like the ideas they are coming up with. A lot of black metal bands think about very different things (undirected hatred, anger etc.), and as such I find it much harder to identify with or enjoy their music. Naturally there are gonna be exceptions to this trend though.
This post turned into a fairly rambling and incoherent mess but hopefully it conveyed vaguely what I meant.
None of this was about aesthetics btw, aesthetics can suck my nuts.
