Oh yeah, it's like that.
The new boss pack came out to add to the wonderful freebies given away the other day. It's all the songs that you battle bosses on, both the boss's and your parts combined.

I was happy to see that this basically became three tracks of some of the most insane solo in the game. I have four starred both the Morello and Slash tracks, and fell at Johhny's Solo R in Devil Went Down To Georgia, but after playing only my new tracks for a day I decided to try to get some of those five stars that I didn't have on my expert career.

For some reason, it was really easy to get some songs that simply baffled me before.

Pretty much everything but 3's and 7's and Raining Blood had become simple.

Also, I beat Through The Fire and The Flames on Expert, yep, helped me that much, that I got through the intro on my 5th or 6th try.

Needless to say, the new pack is wonderful, but I don't need to pitch it because it's free and all, but if you're aching to blow cash and want tracks, I would say that you should either get the Velvet Revolver Pack or get GH2 and get the indie pack.
Im'a go play my ultratar now.
