I'm looking at the album "Dig Your Own Hole" by Chemical Brothers. In fact, I'm looking at two of them. Is there any significant difference between the two? Are they not duplicates? One is obviously cheaper than the other, but they both contain 11 tracks. I see that one is copyrighted by Astralwerks (1997) and the other by Virgin records (2003). So I take it one of them is a re-issue of the original album then?
But it's not a physical thing! So what does a re-issue really mean, in the new world of digital downloads? Is the "newer" album re-mastered? It doesn't say so in the title. Are we expected to assume it's re-mastered? I know that streaming services (Spotify and Google Play Music All Access alike) often carry "limited" or "delux" or "remastered" albums (but they usually state so in the title).
Is the same source file or master record used for digitally transferring the audio tracks to Google's catalog in both of these cases? What am I really looking at when I encounter albums that appear to be identical? Why should I choose one over the other? The price aside; they can even be priced the same.
