I think i'm gonna like it (see what I did here), more "eurovision" is like heaven to me and having the 50 states competing in an annual show like eurovision could be fun. Saying that all 50 states are just "american" would be wrong, there are dialects and flavors (mexican influence in the west states, country music, louisiane and the french language, hawaii or alaska). And to be honest, even if eurovision will always be more different a lot of songs are "radio-friendly americanized" today and that doesn't prevent us to have many different "americanized songs".
I mean why not, Eurovision will always be the best, having a side contest like the junior one is just bonus for us.
