means "I'm alone again". I sincerely cannot think of any songs which title could be translated as such, but I'm sure that other people can be more useful than me about it since my memory is a very weak one. Also, the expression sounds more brazilian than portuguese, but I can be wrong there and anyway it's not relevant at all.
And btw, where the list of songs in italian can be found?

As far as I know, there isn´t a Brazilian translation for How soon is now? called Novamente Só and I really doubt this one is Brazilian but anyway who cares for new versions of those classical songs? well...I don´t, although my good friend and singer Dimitri Rebello did a pretty good cover of There is a Light which I hope will be published one of these days, it deserves it deserves it deserves...you know...

hi Bloke and everyone.

  first of all thank you Bloke for the compliment about my version of "There's a light..." - especially after stating that versions aren't generally worth the original songs...

  and Havfine, i guess i could add some to what you said: it's quite common that song versions, even those that are pretty close translations of the original work, do NOT keep the same title - for it's often necessary to the writer to adapt metric to suit the new language.

  some examples: i have myself 2 brasilian versions for Smiths'songs, and titles are quite different from the original ones (the one from "there's a light..." is called something like "This night (to live and to die in Pelô)", and another one turned "Heaven Knows..." into "True story". also the version from Spanish singer Mikel Erentxun to "Everyday is like sunday" (which is mentioned on the article right above this one) is called "Todo es igual siempre" - something close to "everything is always the same".

  That means, maybe "Novamente Só" IS, in fact, a version to some smiths'song, and it's author just changed the title for artistical purpose. we would have to read the whole lyrics in order to find out which was the original mozz's song.

  well guys hope this helped out in any way

  thanks again bloke and i'll meet you at tonight's rehearsal :]

  also from Rio (hmmm guess i'll go the beach right now :] ),
