In addition, each song has an extra note. The songs are presented in alphabetical order by title. Decrypt the songs and order the songs by the location of the extra notes:

Note Index Song Artist
1 “Ritt der Walküren” Richard Wagner
2 “Eye of the Tiger” Survivor
3 “Don’t Stop Believin’” Journey
4 “Hey Jude” The Beatles
5 “Eine Kleine Nachtmusik” Mozart
6 “Alouette” Traditional
7 “Don’t Stop Me Now” Queen
8 “Escape” Rupert Holmes
9 “Don’t Worry, Be Happy” Bobby McFerrin
10 “O Susanna” Stephen Foster
11 “Never Gonna Give You Up” Rick Astley
12 “Every Breath You Take” The Police
13 “New Slang” The Shins
14 “Edelweiss” Rodgers and Hammerstein
15 “Everybody Wants To Rule The World” Tears for Fears

Acrostically, the titles give the clue RED-HEADED ONE NEE. If you play the extra notes in order, they play the refrain from “Wannabe” by the Spice Girls. Using the clue, Ginger Spice’s maiden name is GERI HALLIWELL. The decrypted songs can be seen here:
