Songs throughout her discography that "go together" for no obvious reason?

What are some songs that, in your mind, are a pair, despite having no obvious reason for them to be? I'm not talking about songs that are clearly and intentionally connected (eg. OOTW and IION?, or cardigan/august/betty) or songs that sound related (eg. mad woman and Cassandra)--I mean songs that don't seem to have any intentional link between them, but you've always sort of put them together for some reason. Bonus points for not being on the same album.

My example: Dancing With Our Hands Tied and Death By A Thousand Cuts occupy the same headspace for me. They're both sad songs that still have a dancey rhythm to them, and are almost the same track number (10/11) on back to back albums, so I used to sometimes mix up which was on which. They sound quite different from each other and don't seem to have any sort of intentional connection, but in my mind they're a pair. (Curious to know if anyone else agrees!)

What's yours?
