NOTE: Unavailable titles will NOT appear in the Catalog page. Therefore, we recommend always checking your Library
if something isn't showing up for you when you search the Catalog.
If you can't find the riff in your Library, check to see if you are filtering out "Archived" riffs. The "Archived" checkbox on the sidebar (where the filters are enabled) will allow you to see just the riffs you've moved to the Archive.
