Toxic
From Tardis Wiki, the free Doctor Who reference
"Toxic" was a popular recording made by singer Britney Spears in the early 21st century on Earth. By the year 5 billion, the song was considered a ballad from Earth's classical era and was played on a vintage jukebox owned by Cassandra shortly before the planet Earth was destroyed. It also woke up Rose Tyler, she having knocked unconscious and dragged by her leg into the room. "Toxic" could be called the last song heard during the planet's history. (TV: The End of the World)
