I don't think MMT is competely dated. It's old and there are some things that you'd never understand or you'd listen to it the first time and say "WTF?!" but you could probably say that for every beatles album, especially SPLHCB, that has got to be the one if not the most dated album there is. Yet, there is still something about psycodelic music that makes you wish bands nowadays would do something like that and make it work like they did.
