What are some songs that have changed their meaning completely over time? Like the Croatian song "Vilo Velebita", the title meant "beautiful tall woman" in the 17th century Croatian, but it has been reinterpreted to mean "fairy of the Velebit mountain" and is now one of the most famous Croatian patriotic songs (even though it originally wasn't patriotic at all).

That's more of a linguistic question, of how language changes meanings across several generations. In my neck of the woods, Faroese and Icelandic have many similar words for mundane things, with almost the exact same pronunciation and even spelling, but drastically different meanings.
