Hmmm...
Fullmetal Alchemist: Both versions have their merits. The first cartoon had a rather facepalm-worthy ending full of cliches, but the music is awesome throughout that series. The second series has nowhere near as memorable music (outside the theme songs), and the first 13 episodes are pretty much recap of what happened in the comics that was kept from the first one. However, I'm really liking the direction of the show now that it's been established that you cannot revive the dead (meaning that Sloth, the worst homunculi from the first cartoon, is not Ed's mom this time. What did she even have to do with laziness?). And the art-style shifts in the show help keep up the manga's humor.
Case Closed: I know. It's been on the air in Japan longer than Pokemon. By this point, Jimmy Kudo could've just waited to grow back up (twice), unless the poison kept him from growing beyond his size. I guess I'm a sucker for mysteries, especially when it includes a hilarious cast. It's probably the same reason I got pulled into the Ace Attorney series of games.
BECK Mongolian Chop Squad: I like rock music in general. I can't say I'm too knowledgeable about it (I only found out recently that Boston apparently doesn't perform well live), but it's great to listen to. The songs in BECK, for the most part, sound surprisingly natural in English, too. Of course, it's also interesting watching Koyuki growing up in a pretty normal life and then aspiring to be a musician. Kinda makes me want to try a little harder for my goals sometimes.
