I think a lot of non english bands sing and write their songs in
English mainly because they all grew up listening to other
bands singing in English.
They're used to certain words in songs etc.
Another thing is that writing in English is a bit "unpersonal".
A poem, or a songlyric is often extremly personal,
so to distance it a bit you write it in another language.
Pluss, for me, when I write my songs, I always write
them in English. Because first off, Norwegian would be
too personal, and second the lyrics would just sound stupid
in Norwegian!We're used to English, and don't really think
about what everything means. Like, do you ever think about
all the stupid band-names there are?!?
I get shocked every time I sit down and think about what
they all mean.. Hehe...
