iTunes - Features please!!!

SEARCH
- ability to search for a song and find it not only in my library but also in any mix i have created. Seriously the search in tunes sucks! i should be able to build a search query "artist = legend" "song=people" and it should say "are you looking for John Legend - Ordinary People?" I should be able to find songs I own by typing in a snippet of the lyrics. I should have lyric search *integrated* into my music experience.

COMMUNITY
- sometimes i find an imix by a user i really like. often i'll click and see what other imixes they have made. often i buy ALL their imixes! really! But you know what i can't do? Select a user as a favorite and then get an alert whenever that user makes a new imix. i really don't get this!! it seems like such a great feature that would totally lead to more buying from me.
I'm just asking for the ability to track users or select "influencers" and buy from them! Maybe they should get an influencer rev-share or something...
The other thing I'd love is recommendations based upon what I'm listening to or my friends are listening to. Seriously. They need Last.Fm.

PURCHASES
Give me a discount if i've already bought a song on an album from you. When you tell me that I've already purchased part of an album -- tell me what I already have!

There's more. but that's all my rant can capture *right now*

(note - original rant was on 5/9/06 ...but time stamp is from when i actually posted it to my blog)

P.S. And please don't tell me they are coming zune...

Update: DC reminded me last night of another feature request: The ability to link to songs in iTunes. I want to find a song and then put a link to that song on my blog or send it to a friend or have my away messagee in iChat or Jabber or Gtalk link to the song in iTunes. Again, this seems like a good way to drive purchases...and community referrals. There is a way to do this today, but its complex and not cut & paste. I want cut & paste links dammit.
