Hi emmdoubleew,
I recorded this piece for the forum(
https://www.pianostreet.com/smf/index.php/topic,15481.0.html)
The first time I learned it at age 13, I learned it and then stopped playing it because I couldnt actually play it through without difficulties. I then took another look at it this year at age 18, and found most of it reasonable. as you can hear from my recording, I cant really play it too consistently and I still dont feel like I "own" the piece. However, I have a hell of a lot of fun playing it, and learning it wasnt too traumatic either.
Definitely, give it a try. Whether you succeed or not, you will enjoy the process of learning it. It's just a really fun piece!
However, you might enjoy learning it even more if you learn some other Liszt first; I actually did have a look at Lecuona's malaguena, and I find it much more awkward than Hungarian Rhapsody, because Liszt was such an amazing pianist and could make really comfortable music for the hands -something lecuona isnt especially well known for-. Therefore, I do not suggest Malaguena as a good "primer," as shasta calls it, for HR2.
I think Joplin's "Maple Leaf Rag" will be a better (and easier) choice to prepare for the 2nd half of Rhapsody, and those Chopin pieces you are already playing are appropriate and comparable to the 1st half, in terms of requirements in legato and appreciation of all the little turn-arounds in the melody.
Also have a listen to Liszt's "Valse Oubliee No. 1"
Hope I helped,
