You'll see a new "Albums" tab available in your profile. This is to list any albums you have available. Currently bandcamp albums may be listed and we should have archive.org installed soon.
It's straightforward to add an album to your profile. The ID field calls for the unique identifier for the album on a particular service. For bandcamp, you can find the id by looking at the embed code. The ID is a number that looks something like "1343691167".
Albums available on Internet Archive are now able to be posted in the Albums tab on your profile. The ID can be found in the URL. For example, the ID for the album at URL https://archive.org/details/TapegermCollectiveGermination2_001 is "TapegermCollectiveGermination2_001". You'll know if you enter it correctly because an embedded player will appear on your page. If not, then try again.
