I don't know! I liked the urgency. I liked sitting down at my computer with a blank slate, knowing that an hour later I'd have some sort of song in front of me.
Silences the inner critic, is the thing. Give me a week and I'll sit around analysing each melody, and going "that's rubbish," and "you're not a real musician," and "everything you write is tat," before eventually packing the whole thing in with the logic that everyone else is better than me anyway. Give me an hour, though, and I'll knuckle down. I'm not going "is this Beethoven," I'm going "is this music?" Doesn't matter any more that it's not Muse, means I'll be happier to just write a brand new bit of robwebster.
And there's not the pressure of how brilliant everyone else is, either. If I know X brilliant musician has a week to write a new track, I won't be interested in contributing at all, cos what's the point? I could spend a month knocking out the kind of song that ClairvoyantCat, for instance, would be able to write in his sleep. If I know X brilliant musician has an hour, though, then hey! We're all working under tough circumstances. We're not aiming for genius any more - what we write is what we write.
