Delete ALL synced music from my devices

[jamesgrant]

Why isn't there a simpler way to delete all synced music from my devices?

Instead of having to go through my list of synced artists, albums, songs and playlists,  there should be a button in settings that simply clears everything! Unchecking every single one is too monotonous and long!

Why is this not a thing already? Surely can't be too difficult to do. Would be nice to incorporate with clearing cache.

It would be so useful when running out of space on my phone or when I fancy a blank slate of music.

Thanks
