First of all I'd like to say that the layout is cool.
I'd write some information on the albums, when they were released and where, which awards / nominations they've earned and so on.
I'd seperate the video section into official videos and fan-covers and create a seperate page for the music samples or link the titles in the albums' tracklists to the sample / video.
I'd also create a page for the lyrics and a page for the different banners with the HTML-Code so people can easily put them into their signatures.
I'd also link to fallforpoets.net, the Spanish Street Teams' Myspace and Wikipedia, however the Spanish Wikipedia contains no article about POTF, yet. I spent a lot of time updating the English Wikipedia-article of POTF, you could use it and translate it into Spanish.
I've got another idea which you could maybe use on this site, too (I don't know if it's useful). Maybe you could create a script on the sample page which allows sending the sample-mp3's to a friend via eMail. Something like:
Send samples to a friend
and the sample-mp3s (or links to them) will be automatically attached to the email. Maybe something like this would make more people introduce the Poets' music to their friends, I don't know.
By the way: I'd also update the "About Poets" article so that it contains every award POT have won. It would simply look more impressive and you could easily see all the awards they've won without having to check out Wikipedia (scrolling through the news archive takes too much time)
Since the non-remastered version of MTIABD has been released as a free song by POTF you should link to it on the samples page so people have a full song to listen to.
