whoa whoa whoa slow ya role there...it's still waaaaay to early to be making prognostications like that lol. Right now he's just another teen sensation inwhich the odds say he's more likely to fizzle out and disappear in 5 yrs than to become a great legendary artists which having a 30-40 career would indicate. Lets wait and see if he can make a successful transition into a young adult star 1st which is no given he can do....

whut iz you Nostradamus or something lol....that's a looooong way away to even be thinking abt...particularly in an era where fans are quick to move on to the next "new thing." The demographic he still mainly appeals to don't really follow an artist's career that long, especially pop stars so he's going to have to make music that grown folks and real music listeners dig.
