well, if you arent in th ebeat making mood... do some maintanance and preparation.
organize your drums, create/edit/tweak some drums, do some mixing on a few tracks, just search for samples, catalog records, label cables if you have a lot of them, organize and clean your hard drive, read up on some mixing/engineering, go out and buy/listen to vinyl, clean your gear, create some templates in your daw, create some patches of you have a synth, learn your daw shortcuts...........
having a block just means that you have time to spend on getting organized and setting things up so that your next few sessions are optimized for maximum performance
