For me it will be little things that will form my ranking. I was very impressed by your entries everyone.
Bloomers:
Avi: I usually see Chris Brown in this type of manner with his music, so I do like the avi
Signature: Its nice.
Playlist:
Best Single: Seeing as you had free reign on the best single choice, I would think Look At Me Now would be his best single, but off of his first 2 albums, I would prefer Kiss Kiss.
Album Cut: You should have just picked up an album cut from Exclusive instead...
Worst Song: Is Poppin' really that bad of an album cut?

compared to other songs on that debut album
Best Video: Its great that it has a storyline, I think Kiss Kiss works here best.
Underrated Song: OH YES. Correct!
Cover Song: I could have seen him do this at some point during the exclusive era, so I see what your talking about.
Thread: I see a bit of talk about his music and success. Flame Beat Z000's comment

Good discussion.
GotSkill: Ahh the 24 hour entry.
AVI: I guess the best of the three is the All The Right Moves avi, but I also like the Love Runs Out one as well since its so moving.
Signature: It definitely catches your eye when looking around at posts and stuff. Nice!
Playlist:
Best Single: Although I prefer a single from the second album, this is a great single.
Album Cut: Its very stripped back. Good!
Worst Song: Meh. That's what I got from the song, meh.
Best Video: from the first 2 albums, yes this is a fact.
Underrated: I see your reasoning, I like Stop and Stare a lot.
Cover Song: Out of all his own works, Bleeding Love? I would have thought Battlefield...
Thread: The best looking member thread did have some interest in the band I guess, so you could have possibly sent that in. As for the thread topic you did choose, I did like the direction your thread was to go into, if only you threw in an artist with longevity with a fanbase on this forum.
Citrus:
Avi: I find its fitting.
Signature:

its very clever when someone goes and reads it
Playlist:
Best Single: its lyrically well done, so I agree.
Album Track: Mr. Mars haha. Good track.
Worst Song: How this was such a hit I don't even know.

Probably was because of the video and it was the follow up to Grenade.
Best Video: Actually I would have used The Lazy Song here because while that song sucks its video is crafty. This is a good runner up however.
Underrated Song:
!!!
Cover Song: This is very fitting with his type of song, he could have better production and serve vocal. Great choice!
Thread: that comment about "you sound like someone's PR...." was humorous, but you went in the direction I would have taken the thread challenge.
ReachOut:
Avi:
Signature: its set up nicely at least!
Playlist:
Best Single: I can see why you picked this song as best single. Great!
Album track: wait this as the best album track? Mid-tempo? This is SLOW. Chop me Up might have been needed here.
Worst Song: Wouldn't it be funny if you had to use his third/fourth album

This is pretty boring, agreed.
Best Video: I can see the dilemma between these two songs you had to choose from. Goodness this is a good song.
Underrated: yes

Cover Song: This answer was very obvious of course. I mean what would he do with the song most importantly since this is a song from his musical influence.
Thread: This is exactly the way to get people talking about his music and him as a whole along with many pressed members. If only Duca actually visited the thread, it would be twice the length.
Era:
Avi: I think it works!
Signature: Hopefully people get the song reference without needing to look at your avi.
Playlist:
Best Single: I would have prefered In The End, it was a formula that worked best for them, vocals with a hint of hip hop. This is like top 3 tho.
Album Cut: Hmm the audience

wow.
Worst Song: Oh I guess we could count this. Wow that vocal effect during the chorus made me laugh, which isn't Linkin's music at all. MESS.
Best Video: Since when did Numb have like 250 Millon Views on Youtube

The In The End or Numb video would have been better in my eyes, this one is decent at best.
Underrated: GOOD!
Cover Song: Wow. This song. I can't even imagine how this song would be reworked to even be a rock song. This really doesn't work for me at all
Thread: You know the comments about "THIS IS WHY ATRL SHOULDN'T JUDGE ROCK" or something along those lines had me

. You got posters in there and talking about Linkin Park. Slay!
Element:
Avi: This does kind of work for me...so what's going on in the background of the moving avi? The Sugar video would have been a great avi to utilize since the band is all up in the video and everyone looks nice.
Signature: Great signature promo
Playlist:
Best Single: Totally agree.
Album Cut: Its great.

Worst Song: Geez

Best Video: This video in a sense reminds of Come Into My world. I like it. Good Choice.
Underrated: I agree. its a good song.
Cover song: I had to dwell on this. Not the most obvious, but it would be interesting to hear from Maroon 5
