For those wondering, the Beady Eye digital store is now offline. It seems like it is now impossible to buy Two of a Kind and In the Bubble with a Bullet in lossless format anywhere. However, you can still buy a lossless version of Man of Misery on Quobuz if you're in one of the supported region.
Hi everybody! I made a discovery after weeks of searching a way to get these B-Sides in lossless format. It turns out that you can still buy the singles in FLAC the official way even if the Beady Eye Store is offline.
Now, how I found this out Apparently, Beady Eye sold their singles using TMStores. This name might be familliar to you : Noel Gallagher's High Flying Birds actually use this platform to sell their stuff. The Beady Eye Store used to redirect the users to the appropriate product page on the TMStore. Using archive.org's Wayback Machine, I was able to recover the URLs for these product pages.
I can confirm that I was able to buy and download these singles. See the image below as proof. If I'm not wrong, this method is also region-free. This means that you can buy/download the singles worldwide unlike Qobuz or 7Digital.
