Spotting Stones - Degrees of Separation, Spotify Style

[The Grand Wazoo]

Spotify - The Related Artists Tab.

How many moves to get from 2 pre-defined and seemingly unconnected artists?
For example:

Elvis Presley to Motorhead in as few moves as possible
Elvis Presley - Rolling Stones - The Who - Deep Purple - Motorhead

Motorhead to Frank Sinatra
Motorhead - Ramones - Beach Boys - Frank Sinatra



So what's the best way to get from:
The Spice Girls to Megadeth?

I did it in 6 moves
