Ah the Tannhauser Overture for Piano is amazing!
The main theme is so uplifting, and everything in between is nice too
And the Rhapsodie No. 2 is great as well, but I think we all know that.
The only other Liszt I've heard was once when Rachel Barton came to visit my middle school were we had a Suzuki strings program set up, she sold some CD's at the end, and not knowing a thing about music then, I picked the Liszt one. I can't say I really enjoy any of the songs on it, but I'd have to give it a listen because I haven't really recently.
