Radio
Artist radio isn't really that great and neither is the user play history (use Last.fm for that). Related artists is great since you can play these directly (unlike Last.fm).

The site is a bit sparse on information regarding the use of the player. A good place to find further and new information is The Pansentient League.

(Web-)Tools

 * If you've already played a number of tracks through last.fm you can set-up an account on Shikaka. Besides all the information on your playing statistics on Last.fm there's the option to get top tracks you've never played from another user's playhistory and have them played in Spotify.
 * FindTheBand It uses the last.fm similar artists feature to find music in Spotify.
 * New on Spotify a selection of new-release albums and singles added to Spotify over the last 7 days. The country codes indicate which territory the album is available in (GB = Britain, SE = Sweden etc.)
 * Playlistify Create your own playlists from different sources (Last.FM, YouTube) that can be imported in Spotify. Or search other users playlists and import them into Spotify
 * Moretrackslikethis Get more Spotify music recommendations, based on your favourite tracks. Results are drawn from the listening habits of 40 million active last.fm subscribers.
 * Pitchify collects reviews from the two excellent webzines Pitchfork and Drowned In Sound on a daily basis, then checks if the reviewed albums are available on Spotify. Only albums that have received a rating of 8 or more (out of 10) will be included on Pitchify. Lots of albums are reviewed every day, and thousands of tracks added to Spotify every week. Pitchify tries to sort through the pile, throw away the Gagas and the Nickelbacks and present you with the very best that Spotify has to offer. Albums that are not immediately available on Spotify will be added to Pitchify's queue, and presented on Pitchify when they become available.
 * SpNotify is a service that updates you on your favourite artists and songs on Spotify. Simply tell us what you want to keep track on and you’ll receive a notification as soon as it’s available.
 * Spo.fm Gets new releases on Spotify based on your listening on Last.fm. When I tried it on my account it got blocked when I set the count to "All" and had to limit it to 350 before I got results.
 * Spotibot Create playlists based on your (or someone else's) music recommendations on last.fm.
 * Spotify forum (unofficial) a forum dedicated to Spotify, and run by Spotify users. They are not associated with Spotify, though represented in their membership. They aim to help users of Spotify make the most of this innovative application, and to help provide information to potential "Spotifiers", to win them over to the world of Spotify.
 * Spotify + Last.fm is a Greasemonkey script that adds a little link next to every artist's name in the form of a green music icon on last.fm-pages to directly search for that artist on Spotify. This also works for tracks and albums. Very handy, it saves on typing and binds Last.fm and Spotify together nicely.
 * Spotify Hunted The 99 hottest songs in the world streamed live from Spotify.

Assorted playlists

 * _Buffer - +8000 tracks
 * Originals that are less famous... then their covers.
 * Indie Now
 * WeAreHunted - new music
