First of all:

Pearl Jam
RadioHead
Red Hot Chily Peppers
Dream Theater
My Bloody Valentine
The list goes on...

All of this bands are, at least for me, the best rock bands in the 90Дs (and in the present)...all of those bands never had any report of alcohol, drugs, animals abuse, etc... So your point fails when u said that 90% of the people back then use drugs, etc...

Anywayz, the only Ozzy song that has a decent lyrics is Hellraiser...

But this is only a matter of opinion, for me the lyrics suck, for you the are good.

So, no point in arguing.
