Last.fm
Last.fm is a service offered that tracks what you play through your media player (scrobbling) and records it to your profile. This is then used to determine recommendations for you based on your most played music. Last.fm actually does a decent job of making recommendations by seeing what you've listened to the most and then comparing that to other users with similar top artists, then making recommendations based on what artists the other users have listened to that you haven't.

Last.fm also features something called a shoutbox, which allows you to leave 'shouts' (comments) on other people's profiles. You can use this to discuss music on a more personal level with friends that you meet (in real life or on the internet), ask for recommendations or just make general small talk. The final major feature of last.fm is the radio. The radio allows you to listen to music based around any classification you see fit, be it a genre, artist, album, song or another last.fm user, though it is currently a service that has to be paid for via a subscription in most countries, with only a 50-song free trial being available in most countries. The subscription also gives other various benefits, such as the ability to see who visits your profile.

Rate Your Music
From the FAQ: "Rate Your Music (RYM) is an international metadata database where musical albums, EPs, singles, videos and bootlegs (collectively referred to as "releases") are added, rated, and reviewed by users. This data is then used to generate automatic music recommendations for users, create lists of compatible users, and to create lists of top-rated music albums. Weighted averages are used to calculate the ordering for these lists; regular members who write reviews and rate more albums have a greater weight applied to their ratings.

Because users can add, rate and review any album they know of without site approval, RYM can be used to quickly and easily to rate any music collection. A welcome side effect of this policy is that the RYM database is extremely diverse, limited only by the collective knowledge of its users.

RYM is also a community, with extensive message boards and the ability to send private messages and music recommendations to other users."

Discogs
Discogs is a website that is mainly for cataloging music. As a music listener, it can be an invaluable tool for finding correct tags for your files. Discogs also provides comprehensive information on album editions (useful if an album's content varies over time or different formats), release formats, band member history and side projects, label catalogs and much more. Discogs also features a recommendation system, which consists of a list of recommended albums at the end of an album's page, but it's more useful really as a music catalog. Discogs also features a very large user-run marketplace, where you can buy and sell physical formats of music. Sellers and buyers have feedback scores and ratings as well as user stores, and items are graded on their condition, much like eBay. Music is also available in digital formats, if that's your thing.

Record Labels
Record labels are an option that a lot of people seem to forget about. By looking at what record label an artist is/was signed up to, you can find new artists that are/were also signed up. A lot of smaller record labels tend to specialise in smaller genres of music, and they seem to try and hold a particular quality amongst the musicians they sign. It's not recommeded looking up the record label of larger artists, since a lot of them will just be signed to more major record labels, who dont take up artists based on style, but based on what will bring them the most money. Some suggested record labels include:

3x3 Threads
First, you need a last.fm account and a history of scrobbles to start. Then, head over to www.tapmusic.net/lastfm, type in your last.fm account name, and it'll generate a collage.

What does (a)/(b) mean? What does + (band name or album), (band name or album) mean? What does - (band name or album), (band name or album) mean? The end result should look something like this:
 * (Number of albums you enjoyed)/(Number of albums you've listened to)
 * Don't be confused if the number is less than 9
 * These are the albums in the 3x3 that you've liked
 * i.e., 3/3 +MPP, Cross, Sung Tongs
 * These are the albums in the 3x3 that you did not like.
 * i.e., 0/2 - De-Loused, People Who

''4/6 + Souvlaki, Cross, Deathconsciousness, On Avery Island - Hospice, Is This It ''

Or, if you prefer, simply this: 

''+NMH, Strokes, HANL, SY, Justice -Burst Apart, Brand New''

*Note: there is some use of ~ instead of a + or -, which denotes only partially liking an album. This is the equivalent of 0.5 of an album when giving numerical ratings.

Chart Threads
Chart threads consist of users posting their top 50 or top 100 albums which are then rated or given recommendations upon.
 * Charts can be made at http://topsters.de/
