Andros and Tides are pretty much the same planet. It's called Andros in the 4Kids version. As for the wings, they can either be enchantix/believix or fanart.
By the way, next time, I think you should use the answers section. Thanks:)

idk what the answers section is
and also, why are their voices all messed up in the 4th season?

Look closely at the front page. The answers section is under the picks section.
What do you mean "messed up"? They sound pretty normal to me. What version are you watching?

i watched the first three seasons of winx and their voices were fine, but then when i found the fourth they were different, here ill show you:
normal (season 1): link
weird (season 4):

The answer to that question is that you've probably grown up with the 4kids dub, and season 4 hasn't been formatted by them. It's only been dubbed in Italian, and Rai English. (And other languages, but 4kids has not dubbed season 4)

Tho the voices might sound strange, Rai English is the only English version we got X3 So, who cares if they sound strange; We can watch season 4 in our native language xD

Oh, and the "Answers" page (As MelodyLaurel has explained) you can find by clicking link

the voices make me sad tho, they arent the ones i know they are like diff girls :/

Yeah, they are different. I don't prefer Rai English that much to 4kids, due to that the voices are awful :P But, I really hate reading subtitles for the Italian episodes, so I guess it'll have to do.
