to me yes 2005 and 2006 are not technically ''m2m'' era because m2m came out in 2007 and then they toured for it for 2007 and 2008. well someone has made a post on this era thing before somewhere on reddit.com and I think they said it good. i will try and look for it.
edit post: ultimateguitar.com brad delson says they started writing m2m in november 2005. plus brazil 2004 mike said it was final show of meteora tour. 2005 and 2006 seem to me to be more of non album year, just the band live, but not supporting album. 2009 is this too for me and maybe 2016. projekt revolution tour woodlands 2008 mike also says it is last show of m2m tour besides the china tour in october.
but yes if we get japan 2006 tour as part of meteora i would not complain!! it's all good music either way 😃
