The number of music sites worth signing up for keeps growing. If you're as disorganized as I am, a morning's listening can make a mess of your desktop, and the different interfaces for each site make hopping around among iTunes, Grooveshark, imeem and Pandora awkward.

Twones -- pronounced like "tunes" -- makes a Firefox / Internet Explorer add-on that unifies 25 music services into one interface.

Twones also claims to be a rich source of information and bonding experiences built atop the music links, but it's nowhere near last.fm's seemingly infinite amount of user-contributed content.

What matters most is Twones will track all of these services in a common interface:

  • Last.fm
  • MySpace
  • Deezer
  • Muxtape
  • Seeqpod
  • Favtape.com
  • Finetune
  • Joost
  • Grooveshark Lite
  • Hype Machine
  • iTunes
  • iLike
  • MOG
  • imeem
  • Winamp
  • nuTsie
  • Ning.com
  • YouTube
  • Luisterpaal 3voor12
  • SkreemR.com
  • Windows Media Player
  • Songza
  • Pitchfork.tv
  • Play.it

Pandora support is coming soon, a company spokesman told me.

If you're looking to bond with a bunch of fellow music fans, or go data-diving for everything there is to know about Architeq, last.fm is the Alexandria library of info. But Twones performs one function well: It consolidates your music interfaces, which makes them easier to use, which saves you time fussing with them, which lets you spend more time listening.
