These services get their information from the same place we do, a company called Xperi (formerly Rovi/TiVo) who create and provide album and artist information to us. Please see the details on submitting information to them on our
Product Submissions page.
Unfortunately if one of these services has incorrect information about an artist, there isn't anything we at the website AllMusic.com can do about fixing it. It needs to be corrected by the company that provides the info to all of these sites and services.
There are also situations where Xperi may be sending the correct information to one of these services, but it is getting mixed up at Apple or Spotify or wherever. In that case you would need to contact that specific service to get it ironed out.
Xperi tries to add artists and recordings, as well as review as many CDs possible, but can't make any promises about which artists and titles will receive this level of enhanced editorial coverage. However, you may send them your information for consideration by following the steps on the
Product Submissions page.
