Recently I bought a single track from an EP, then later wanted to send it to a friend as a gift. I was completely flummoxed because the “Gift This Album” link did not appear on the page. For a while I believed that it had been disabled intentionally because the record label didn’t want it given as a gift! But I knew that made no sense.
Eventually I figured out that it was because there was an offer on the page for me to “complete” the album by purchasing the other tracks, and that there was a link available for me to view the full album. But why change the page and eliminate the highly-visible gift button? This is an unnecessary inconsistency.
