Personally, I loved playing "A Jagged Gorgeous Winter", "Night Lies" and "Conventional Lover" on RB2, while I loathed playing "Visions" on anything apart from vocals. No offense to your co-workers, I'm sure they're awesome people, but some make the kind of music I enjoy while others do not.
Now, when these HMX songs were excluded from the all or nothing RB2 export, I think a number of people (myself included) were under the impression that we'd be able to get back the songs we loved, while being able to say farewell to the song(s) we didn't particularly care for. Regardless if they were for free or not.
I hope this response is helpful in some sort of way. Rock on! \m/
Edit: Looks like Magnet beat me to it. But I still hope this post is helpful to someone somewhere.
