11. Another option is to share a playlist that others can comment on and contribute to. Simply right-click a playlist and choose ‘Collaborative Playlist'. Bear in mind that Spotify Free works only in the UK, Sweden, France, Spain and Finland at present, so friends outside these countries can't join in.
12. If you're particularly keen to expand your music listening, Feelinglistless suggests subscribing to music-related RSS and blog feeds. Often, an artist is reviewed one day, then their music appears on Spotify a day later. You can also request additions at weekendlabs.se/index.php.
13. Spotify add-ons have started appearing - mixtapes have a kooky retro appeal with their ‘made it myself' appeal, for instance. If you're a Facebook user, search under Applications and you'll find something called Mixifier. You need to allow Mixifier access to your Facebook account.
14. Add your own mixtapes to Mixifier by entering their http codes. As with Spotify, you can view popular, brand-new or highly rated playlists or search within the listings. Click a playlist heading to bring up options to play it or to send it to Facebook friends - just enter their names to do so.
