I have made no changes to my settings, nor have I upgraded anything...
Suggestions...?

To add the spotify repository's key, run

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 082CCEDF94558F59

You can remove the cdrom from your sources with

gksudo software-properties-gtk

Other Software tab, untick the boxes next to cdrom:
When you're done, run

sudo apt-get update

and there shouldn't be any errors.

Those sources are either no longer offered or down at the moment. So just use your software sources and uncheck them.

thanks a lot for your reply, that indeed fixed the problem for me (to be honest, in the meantime I had also found this help page http://maketecheasier.com/fix-the-pa...ntu/2012/06/22 )
