I personally wouldn't put Taiyo Yuden in the premium spot. (much to high fall out rate because of bonding problems. )

(Probally a controversial opinion I know.)
Also the claime for verbatim is bullshit. Made In japan would mean TY in most cases and personaly I prefer the singapore and CMC stuff over TY these days.
Then the next becomes more funny.
How the hack did Thats Write,MAM-E and MAM-A and Emtec get up to recommended.
Incase of That's write and Emtec they probally sell quite bad performing optodisc media.
Also for some european folks it will be a mystery how optodisc can be named recommended but also for some american folks it seems a mystery when it comes to the ridata recommendation.
Ohh and in the case I would put TDK one level up.
Also funny is that Princo and sky and moviestyle are not put under landfill.
Moviestyle is made by infosmart which itselff is called landfill. hmm
Also primeon is funny qualified. All primeon's media is these days made by MAM-E which was recommended media. Hmm as you can see these lists allways contain errors.
Now if people really want to make such lists then they would have to keep a eye very good on the market and keep changing and improving.
I know this is really time consuming.
In all the other cases it's useless.
