I agree with a lot of this Marilyn. It is easy to forget that the classic oldies are classic because they have been around a lot and gained respect over the years..if they were worth it in the first place, and time does tell!
While I still think it is too early to describe LICM as a classic album, it's certainly a very very notable debut album, and while in my opinion it's a little strange for it to be sitting at the top of this poll (I don't mean to take anything away from Mika here), I do actually think that it simply being up there is good for Mika's credibility...people will see the album up there and maybe wonder about it, just maybe take Mika a bit more seriously. That's especially important during this Mika "downtime".
So these subjective poll things aren't a bad thing ...they should just always be taken with a pinch of salt.
