Can you think of any artist who hasn't ever released a bad song? I can: Elliott Smith. This guy was a breathtakingly talented acoustic artist who took his influences from The Beatles and the Beach Boys. His music isn't as cheerful as that though. I mean the guy killed himself so yeah. I have yet to find someone who dislikes Elliott Smith's music. Don't be that guy.
These are widely considered his two best albums.

Elliott Smith - Either/Or
Elliott Smith - XO
