For the band, recently I've been writing lots of tunes when I'm high, never used to do that, but that just seems to be my most creative time at the moment. I try to never "plan" how a song will go(for lack of a better phrase) as I'm not really for convention song structure due to my main inspirations. I have a few times hummed a riff onto the recorder on my phone, but due to the ridiculousness of the intended riffs, it's hard to hum it. Lyrics wise I just start jotting stuff down when need be and I see where it goes, it never tends to be about feelings/experiences, most of the it's some total nonsense. I rarely get ideas for them and jot down on a napkin or something, for me lyrics have a time and place to be written as they're the least important part of the music to me. I've been doing a lot of solo stuff just now, just as a side project. It's experimental (ala Fantomas), so it's hard to write that stuff at times although once the brain gets going it's simple as you can really do whatever the fuck you like with it. I've tried to lay tracks over, say, 5mins of a film/cartoon, changing tempo/style/mood etc depending on what's going on. It's quite amusing.
