If I am thinking about anime converted to live action that would be Initial D. My son loved the anime (and I enjoyed it also) the live action was a different take on the story so I kind went .... hmmm.... interesting as an alternate reality but not a true to the story adaptation.

There was also a "Great Teacher Onizuka" live action but we are going way way back in time with that one. It appears to have been an adaptation to a live action TV series from the anime. I was only able to find one or two episodes which were fan subbed. Great for what it was but we are talking mid 1990s so a long time ago :)

Other anime to live action? City Hunter was an excellent remake :) Well, the Jackie Chan one is very different than the Japanese one. Maison Ikkoku had a live action remake but I didn't see much of it. One Piece was good live action but I never saw the anime. Same as Cowboy Bebop good live action but never saw the anime.

As for the absolute worst anime adaptation.

Would have to be Sailor Moon M

That was just wrong....
... very very wrong

Hilariously wrong.

And as for the Avatar movie? I think I would need to rewatch the series first to catch up :) My mind doesn't remember the details like it once did.

As for listening to anime music?

Megumi Hayashibara. Voice Actress and singer. Loved her stuff (Give a reason is one of my favorites from her). It's pop so not likely your style but yeah, I like anime music :D
