Music Legends 2: One Hit Wonders Mystery Cache

With the original having caused so much brainache for so many, I thought it only cruel to bring on the sequel.  I'm being a little nicer this time though, and allowing you to solve all of the clues before needing to search out the location of the final cache.   Needless to say, the cache is not at the listed coordinates. Have added an instant scratchie for the lucky FTF

Punish your ears and eyes with the following three clips (well, I actually like one of them, but the other two are really pretty bad - you can try and guess the one I like).  There is something all three have in common, which, when you figure it out, will lead you on to three music artists' names.  The first letter of the first and last names of the people concerned can be converted to numbers as follows:

A,R,Y = 1

D,F,P = 2

C,Z,W = 3

G,Q,T = 4

O,K,V = 5

S,E,I = 6

X,N = 7

B,M = 8

J,L = 9

H,U= 0 

First names are used to work out the south coordinates, last names the east.

Cache location is at S34 01 xxx E151 04 yyy

The first clip will lead you the first digits in each number:

The second one will give you the middle digits in each number:

Clip 2

The last one will give you the last digits in each number:
