Final answer:
The question does not provide a clear answer, but in a broader context, Elvis Presley, while not an option given, is a prime example of an artist influenced by country music but not confined within its establishment.

Step-by-step explanation:
The musician whose music sounded like country but never truly became part of the country music establishment, as listed in the options, cannot be definitively determined without further context.
However, if we look at the broader music history, artists like Elvis Presley, who is not mentioned in the options, were deeply influenced by country music and rhythm and blues. Presley merged these styles to create rock 'n' roll, a genre which found roots in various musical traditions including country.
Other artists such as Carl Perkins, known for "Blue Suede Shoes", also merged country and rhythm and blues, creating music that topped multiple charts and appealed to a diverse audience.
Perkins' music exemplified the hybridization of musical styles that characterized rock 'n' roll. Similarly, Presley's early records combined regional styles like R&B and bluegrass, showcasing the versatility and innovation of these musicians who straddled genre boundaries.
The specific question regarding an artist like Bob Dylan could hint towards an artist who was known for his folk and rock music rather than traditional country, but who incorporated elements of country music into his work.
Dylan is recognized for his poetic and narrative songwriting, which often included storytelling elements characteristic of country music but existed outside the conventional country establishment.
