It's a potential can of worms this Nos
We'll all have a different opinion on best songs which is good!
Do you know what though, willingness to learn is such a great thing, and even just searching for the band's name on YouTube will open so many avenues for you, we all know about the YouTube rabbit hole of watching one video and three hours later after clicking on recommended things the evening has vanished
Do you use any music streaming services? I know that Spotify and Apple Music for example make 'essentials' playlists with 20-30 songs from a band to get you started, I've found that with the bigger bands that have 10-15 albums these are such a boon as you get to listen to listen to a bunch a things spanning their career and then you can cherry pick and listen to the full albums.
Good luck, and let us know what you found and what you like
