Rio–São Paulo high-speed rail: The Rio–São Paulo High-Speed Rail (Portuguese: "Trem de Alta Velocidade Rio-São Paulo" ; Abbreviation: "TAV RJ-SP") is a planned high-speed rail project to connect São Paulo and Rio de Janeiro.  While originally planned to be operational by 2014 in time for the 20th FIFA World Cup to be held in Brazil at a cost of $9 billion, as of May 2015 formal bidding for the project had yet to start, with the Brazilian government delaying the auction by "at least" one year in August 2013, pushing back hopes of completion to at least the 2020s

Ti Voglio Qui: "Ti Voglio Qui" is the second single by Australian pop singer Tina Arena from her 1997 album "In Deep" and the Italian version of its hit lead single Burn.  As an alternate language version of a hit single, this release lacked substantial mainstream appeal and therefore failed to make any significant commercial or chart impact unlike its highly successful English counterpart.  Despite being released at the same time, the two songs are often credited as the first and second singles from the "In Deep" album.  It is credited as a single released from this album due to its connection to "Burn" and the two songs' simultaneous releases, despite being a non-album track.  This quickly made its limited CD Single a highly sought-after collector's item, as it was the only way to obtain this song until it was re-released on the limited edition 2CD version of the "Greatest Hits 1994-2004" album.  Although this version of the album is now out of print, the song can still be purchased from a number of Australian legal music download services.  A Spanish version of "Burn" was also recorded and released as a bonus track on the versions of the "In Deep" album released in a number of South American countries.
