Hello friend aurzeq very good evening.
Here strolling in the community I saw your post and I stopped to read it with a smile hahahahahaha.
It brought back so many memories because as a fan of anime and I have also seen a lot among my favorites are the ones you mention.
I imagine of course you know many others of this style, because the ones you show are already real classics and now there is a wide list of new anime, also good, but that direct attention to new consumers of anime.
and do not allow them to enjoy these spectacular stories.
Dragon ball is perhaps the most famous in the world and has new editions so many new audiences know about it and have taken the time to see what it was from the beginning but the others not so much.

Fullmetal Alchemist: shintetsu, although somewhat different from the previous work Fullmetal Alchemist, is another work of art that entertains and opens the mind to concepts that seen from another perspective are so deep that scare. both fullmetal are recommended to everyone but in my opinion the plot of the first one is a little darker and sadder and I agree with you that: they are perfect.
The super classic Cowboy Bebop. i can't say more that apart from its great story and ending, its soundtrack is unforgettable as you already mentioned. everyone who watches and likes anime should watch it.

Death note was something that came to my hands like that: On a day starting in a new job, talking to a new acquaintance about hunter x hunter and its psychological aspect, he mentioned it to me and agreed to show it to me. the next day he came with two CD's hahahah. he put them on a table in front of me and just said: watch it.
A great gift because that series taught me another way of thinking more analytical. I have seen it 6 or 7 times hehe.
A big hug brother and thanks for your post...
