The Music Puzzle

One page in the puzzle booklet showed the following:

A cassette tape was also included in the packet - hunters were clued in that this cassette was relevant to this puzzle by the music note at the top of the page. Contained on the cassette were very short snippets of 21 popular songs. Identifying the titles of these songs and inserting them - in order - into the blanks on the page yields:

W	Tutti Frutti
H	Kashmir
A	Respect
T	Every Breath You Take
A	Once In a Lifetime
R	Surfin' Safari
E	New Years Day
M	Daydream Believer
Y	Surfin' Bird
P	Wild Thing
H	Tom Sawyer
O	Across the Universe
N	Paint it Black
E	Taxman
N	Shock the Monkey
U	Somebody to Love
M	The One I Love
B	Rio
E	My Generation
R	Sympathy for the Devil
S	Love me Tomorrow

Following down the list of letters at the left of the page, the clue reads:

What are my phone numbers?

The "phone numbers" are the numbers on a phone dial corresponding to each of the letters listed down the left side of the page.

Converting the letters in this fashion results in:

W = 9	Tutti Frutti
H = 4	Kashmir
A = 2	Respect
T = 8	Every Breath You Take
A = 2	Once In a Lifetime
R = 7	Surfin' Safari
E = 3	New Years Day
M = 6	Daydream Believer
Y = 9	Surfin' Bird
P = 7	Wild Thing
H = 4	Tom Sawyer
O = 6	Across the Universe
N = 6	Paint it Black
E = 3	Taxman
N = 6	Shock the Monkey
U = 8	Somebody to Love
M = 6	The One I Love
B = 2	Rio
E = 3	My Generation
R = 7	Sympathy for the Devil
S = 7	Love me Tomorrow

These numbers correspond, in turn, to the nth letter in the song title listed. Highlighting the nth letter of each song title as described yields:

Tutti Frutti

Kashmir

Respect

Every Breath You Take

Once In a Lifetime

Surfin' Safari

New Years Day
