I haven't been inspired by music in so long. I don't even listen on public transport any more. I'd sooner listen to the rain beating against the side of the bus, or half-overhear snippets of people's life or work drama.
I know exactly what it is; it means I'm about to get depressed. I always lose interest in the things I love when I'm getting depressed, but music is usually one of the things that helps me. Don't really know what to do without that.
