They were sold one at a time as part of a promotion for the album. They are not an album in themselves. My mp3 player has a similar folder to above as the tracks were presented here through someone's kindness as they bought and shared them.
If you have a source that has them bundled together as an actual album via official sources, I'd be extremely keen to see it - that just appears to be an iPod with the stuff here place in it.
Other than that, this was done to direct people to the Smiths 'official' web URL, generate hype for the box set and included some online 'memories' via hashtags. I don't believe that any of that was to include a selective live date release to be included with the main offering.
Not all 'shop' routes to these sold MP3s even list all of the tracks for sale and don't forget Take 1 of TIALTNGO & Rubber Ring/WSS Great Woods Center were also offered in the build up.
It was a marketing ploy to generate interest with a bonus that people could give them extra money for one-offs.
Thank you very much for the fast reply ! I read it immediately but as on a hurry, I forgot to answer ! No there not an official source. What intrigued me was the Album name tag and that's why I rushed in to the forum; if the songs are only gonna be "released" individually, for me album name tag should be as given in the same way as displayed by spotify (ie "Some Girls Are Bigger Than Others (Live)").
