"We need your help testing Line-In--our new metadata crowdsourcing platform.
Line-In is a tool that allows our most trusted fans and music lovers (like you) to suggest edits to the information we have about artists, albums, and songs on Spotify. This will help improve, extend, and confirm the data describing music - which will in turn help us improve experiences for Spotify Users and the Artists creating the music on Spotify.
To help us test this tool please click on the SIGN UP botton below. The first 150 to sign up will get access."
It seems that you can still apply in that thread if you want to help. You can also click on the links inside the tool for What is Line-In? and FAQ.
It's been my biggest dream to be able to edit and improve Spotify!
I usually don't check Getsatisfaction really every day, but luckily I did yesterday!
I didn't use to check Spotify Community more than once a year, but now I will check it (and Getsatisfaction and Line-In) every day, 365 days a year!
Yesterday I started to systematicly go through my last.fm Library (first my artists in falling order) at Line-In.
I've just finished my Top 500 artists, answered 6 Surveys and made 675 Contributions in total.
I haven't made much difference yet, but I've reported that 2 artists were the same artist.
And there is a new board in their Community for it:
There are often times when a track is misspelled or contains extra messy information. Sometimes, these problems also affect album titles or artist names. Issues like this are the responsibility of our content partners to correct, so our only recourse is to send the issue up the chain and ask the label or artist to resend the metadata. Please be patient while we build a nice interface to gather this kind of feedback and get it to the right people.
Errors should be reported with a support form like before Line-In was introduced:
