So, just for the fun of it, I did some math to see how much of the canonical catalog we will have when Rubber Soul DLC releases.
If you count 44 tracks on disc (counting Sgt Pepper and With a Little Help as separate songs, but excluding the Within You Without You mashup since its not technically part of the Beatles "canon" defined here as the original 13 albums (including the American compilation of Magical Mystery Tour) plus Past Masters (which comes to a total of 212 songs if you discount redundant tracks like single vs. album version of Let It Be and Get Back, and the German singles, etc.)
Then add all songs as separate songs but avoiding repeats from Abbey Road (i.e. Sun King/Mean Mr. Mustard = 2 songs, Golden Slumbers/Carry That Weight/The End = 2 songs, since The End is already counted) comes to 11 for Abbey Road,
then 8 for Sgt. Pepper, and 11 for Rubber Soul.
We get a total of 75 canonical tracks in game divided by 212 and multiplied by 10 comes to
35% of the entire Beatles canon.
I'd say it's pretty impressive that we have over 1/3 of the entire catalog (which would be 33% for you younger folks who don't know math) in just a few months of the game's release.
Good job, HMX.
