Well that's implied.

Agreed. And take drugs too.

Get bored. Take a dump.

The key difference Ive seen between good musicians and productive good musicians is that the latter keeps making music even when they aren't inspired. Its ok to make shitty music as long as you just KEEP WITH THE PROCESS OF MAKING MUSIC. Its perfectly ok to make 80% crap as long as you keep practicing your chops.

This is my routine.

I find that these is one of the easiest ways to just write something for the sake of writing

just make yourself do it.
easier said then done but it's that simple. find what inspires you then create whatever you want. i don't listen to other people's music while i'm in process of writing a record, it's distracting.

also, drugs or not: if you find yourself being lazy, stop it. drugs are one of the most powerful tools for creating things in the hands of the right people, but i find that most people i encounter lack the self control/attention span to sit down and work on things for more than a few hours at a time.

Yes. This! What you said! I'm going with this. It's so obvious now that I think of it. That's why people bought my paintings in the first place. All my influences came from stuff that was nothing like my own. Thank you, man,

That's usually counterproductive for me. I get ideas, but get lazy.

I just got my computer fixed and running like new. Now, I'm going to get started with stuff. Slowly, but surely.

Echoing the sentiments of many other, longevity really does work.  Even if you aren't working especially hard, your tracks will get better as your taste, ability, and knowledge all develop.

overload yourself with books, plays, stories, friends, films, graphic novels, adventures, and non-chipmusic. (if the main influence for your chip music is chip music, your music is going to sound like a pile of derivative shit. explore different genres. 'radiohead' is hardly bottom of the barrel stuff, expand yourself on to new music. i mean, if you aren't taking the chance with other obscure niches of music, why would people want to listen to yours?)

vary your influences, always write, whether that's words, drawings, music - just keep working, and it's hard to get shitter.

Drugs

Staying up late seems to help too. The guilty pleasure of knowing tomorrow will be shit but you're having too much fun

"just five more minutes, I'm on a roll here, can't break my creative flow >now<"

I've been pretty unmotivated to write anything recently, though I have been busy with real-life things.
Just take what ever is in front of you, and deal with it. Music ain't going nowhere.

^kind of a hippie answer, but if you don't know where to take a track, just let it go where it wants. if it doesn't sound like any other song you've heard before, good. that just means you have artistic individuality. if nothing else works, save it, forget about it, and pick it up again another time.
