The 'Why'd You Only Call Me When You're High?' singer has no fears his skills as a songwriter are running out - even after making five albums with the band in eight years - but if they did, he'd turn his hand to horticulture.
Alex told NME magazine: ''I don't have time to worry about [not writing songs] to tell you the truth. I think there's always that thing, maybe it will just like, disappear? And I could do some gardening or something?''
The frontman also compares his songwriting process to the impending arrival of a delivery.
He explained: ''Writing songs for me is like waiting for deliveries. You get a window: the washing machine's got to be there before 11 and 5. You've gotta wait for it. [The song] is the washing machine, the idea. You're like, 'Right, we're gonna do this record between now and then, and in the middle something is gonna arrive.' A loosely metaphorical washing machine.''
Arctic Monkeys' fifth album 'AM' is released this week.
