Re: what borderline things will you be claiming for this year?
I would expect that, if said music subscription was only available on work devices, in the "office" (home office may be dodgy), one could claim it was "wholly and exclusively" for business use. It's flying close to the wind, though, and HMRC would probably come back with "even though you only use it for work, you could use it outside for personal use, so jog on".
