Purchased album only partially downloaded, so I troubleshooted in order to attempt a re-download of the full album, now I cannot download any of the songs.

I purchased an album just now. 4 out of the 12 songs downloaded and then it sat there trying to download for 20mins. So I went to Accounts>Purchased, and saw that there were no outstanding songs that needed to be downloaded. I then:

• removed the album from my library (for some reason it was "split" over two albums (it's a single album, but Music did that thing where it splits the songs over 2+ albums because of 'album artist' settings or something. In my case tracks 1, 3, 4, 12 on one, then 2, 5-11 on another, with a mix of downloaded and not downloaded in each);
• closed Music, reopened it;
• went to Accounts>Purchased: no outstanding purchases needing to be downloaded;
• went to iTunes store, went to this album: it says "Purchased";
• closed Music, reopened it. Same deal.

Now i have an album I have purchased, with no apparent way of downloading it... Help!
