Back in September, Apple released iOS8 alongside the iPhone 6, featuring a myriad of new options and features alongside space constraint issues for those with the lower capacity models.
If you weren't already aware, one of the new cool features available is the ability to rank your music artists and albums by their size taken up on the device. If you're worried that your previous, or current, love for One Direction or Taylor Swift is taking up too much room on your smartphone, you can see exactly how much of your precious (and limited) storage capacity they are eating away at).
To take advantage of this handy feature, all you've got to do is navigate to your Settings app pick General, Usage and Manage Storage. From there you can browse what's on offer.
Press Edit if you're wanting to make any changes to what you can see, otherwise sit back and feel happy that you've gained some somewhat-useful but mostly useless trivia knowledge.
