The Hack

The passwords hacked in 2012. (via

In Mar 2012, was breached by hackers and more than 43M user accounts were compromised.

The full extent of the hack, and its connection to similar attacks against Tumblr, LinkedIn, and MySpace in the same time frame, were not confirmed until Aug 2016.

The passwords were encrypted using an outdated, unsalted MD5 hash. Three months after the breach, in Jun of 2012, issued the following statement:

“We are currently investigating the leak of some user passwords. This follows recent password leaks on other sites, as well as information posted online. As a precautionary measure, we’re asking all our users to change their passwords immediately.”

The input could come through an Audioscrobbler plugin or a station.

The sites also shared many community forums, although a few were unique to each site. The old Audioscrobbler site at the domain name was wholly merged into the new site on 9 Aug 2005.

Network Features

User profile

User profile
						 user profile. (via

A user can build a musical profile.

  • By listening to their personal music collection on a music player application on a computer or an iPod with an Audioscrobbler plugin.
  • By listening to the Internet radio service, either with the client or with the embedded player.

All songs played are added to a log from which personal top artist/track bar charts and musical recommendations are calculated.

This automatic track logging is called scrobbling. automatically generates a profile page for every user which includes basic information such as their username, avatar, date of registration and total number of tracks played. There is also a Shoutbox for public messages. Profile pages are visible to all, together with a list of top artists and tracks, and the 10 most recently played tracks (can be expanded).

Each user's profile has a 'Taste-o-Meter' which gives a rating of how compatible the user's music taste is.

Artist pages

Artist pages
																Artist pages on (via

Once an artist has had a track or tracks "scrobbled" by at least one user, automatically generates the main artist page.

This page shows details of the total number of plays, the total number of listeners, the most popular weekly and overall tracks, the top weekly listeners, a list of similar artists, most popular tags, and a shoutbox for messages.

There are also links to events, additional album and individual track pages and similar artists radio. Official music videos and other videos imported from YouTube may also be viewed on the relevant artist and track pages. currently cannot disambiguate artists with the same name; a single artist profile is shared between valid artists with the same name. Also and its users currently do not differentiate between the Composer and the Artist of music which serves for confusion in classical music genres.


																Charts on (via

One particular feature of is the semi-automatic weekly generation and archiving of detailed personal music charts and statistics which are created as part of its profile building. Users have several different charts available, including Top Artists, Top Tracks, and Top Albums.

Recommendations features a personal recommendations page that is only visible to the user concerned and lists suggested new music and events, all tailored to the user's preferences.

Recommendations are calculated using a collaborative filtering algorithm so users can browse and hear previews of a list of artists not listed on their profile but which appear on those of others with similar musical tastes.
