Looking for a site that will tell me which albums I don't have.
 

Basically I'm looking for a site or tool to which I can upload my library and will then give me a list of all the albums of those artists which I don't have.

Albumspotter.com should do it, but only shows me the most recent or upcoming release.

Cheers.

go to wiki, and search _ year for music from 1857-2011. Most of them will be on there.

Groovebug is an ipad app that does something very similar to that. I don't know if they have a website that does the same thing, but I have to wonder why you want to upload your entire library when you can just do it manually by going to a decent discography site, or using the itunes store.

It's time consuming, but if all else fails, you can use rateyourmusic.com to see what you don't have by each artist you listen to.

Ok, I guess just going through it one by one isn't going to be the end of the world.

Cheers.

I actually enjoy that process.

Yeah, the process of discovery is all part of the fun of being a music lover. Why collect music if your having a computer doing all the discovery for you?

Yep, fair point.
