Why is Michael Buble's Music so fun?

Michael Buble has redefine Big Band style music. He adds a contemporary touch to each old fashioned song he sings. He sings many love songs, and most of them are older, he sings them like they were sung in the twenties or thirties, but he adds his own touch to make it a little more exciting and personal. Michael Buble is young, so he appeals mainly to younger women. I think it is interesting to see how he is happy to sing what he enjoys, and he doesn’t conform his music style, or change it to be more appealing to the bigger musical genres. He has no heavy metal electric guitar, or screamo background vocals, it’s just how it used to be. I think he has given the younger generation a taste of how it used to be because his music is very nostalgic. He also adds a little humor to his songs, and music videos which always makes it a little bit more interesting.
