Specific artist sound modelling - advice needed.

Magicman

I’ve just taken up playing electric guitar after around 10 years break so very much ‘out of the loop’ when it comes to Guitar effects. 
What I want to buy is something whether it be a physical unit / software / App that can, to a good standard of accuracy, model specific Artist and songs as a pre-set that I can very quickly activate. 
For example: Brian May - bohemian rhapsody
Gn’R- Sweet Child of mine, Nirvana - teen spirit, etc etc....(you get the idea)

ive seen an old amp - Fender G Dec for which you can buy SDcards which replicated the exact sound for specific songs and artists such as listed above. 

I dont have the knowledge edge or interest I experimenting trying to ‘find that sound’ just want something that I can easily click a pre-set to model sounds. More than happy to buy such a pre-set that has been programmed by a professional but I’m so out of touch with all the latest gear in the market, I would really appreciate any of your experience and advice.
