umm.. any ideas?

Well, here is one I've been thinking about. It seems a little impossible but still it's an idea, nope?
I wish the net had a site that had every kind of food with pictures and tastes. Let's say, you're going to go out to some fancy cafe with people you want to impress; wouldn't that be great to be able to nibble a little of that food and be sure how it tastes like?
Or let's say you're traveling somewhere, and you need some good advice on food: what to eat, what to avoid, what NOT to be scared of.
As a solution: well I'm not sure what I can offer but here's something I've heard a while ago. Every taste refers to somewhere on our body. When the nerves referring to that body are triggered, we feel the taste in our tongue.
This just sounds creepy..

A map of everything.. Wouldn't that be great? I know that's way too general but let's say it's a map for a city you have never been to but planing to move to. It can give an idea about the best restaurants, the rent rates, the crime percentage, the live expenses and etc.
Obviously everybody is moving somewhere new and most of the time they come across with problems which has a lot different answers. Moving in New York is a good example actually; let's take someone who has no idea about New York but just got accepted from school. Getting to know the city for living but not for touristic purposes can have hard consequences. What if we had a website that could list the security, rent rates, deli's, living expenses of five boroughs? Wouldn't it be easier to find a good spot to live? Not only for New YOrk of course, it's for all over the world.
It's not that hard to build up a database for this, anybody who has access to the internet can write down a couple of lines just like in urbandictionary.com or answers.yahoo.com and voila, there's your database.

I heard this project was coming to life but I couldn't find it online yet. It's not online or it's my poor search skill..
I wish the net had a site that can let me sing in and find which song I've been singing for a week. There's always a song stuck in your mind and sometimes this song can be foreign or just the instrumental part of a song. When the lyrics are stuck in your mind, it's not a huge deal to look it up on the net, but when it's the instrumental part, it's just messed up. I've heard that they are building up a database of songs for a website where you can sing right away with your mic and the website will be able to pull up that annoying song you've been singing since you got up.
In a way it's like myheritage.com's celebrity finder, just a little bit different than that.
