Code Breaking Competition 2.0

[Nitrus]

Ok, so after the very impressive hast in which Chris managed to decode the message last time, I decided to move away from common techniques and devise my own code.

This time the decoded message is a riddle, which you have to solve in order to win.

Rules
1. The first person to reply to this thread with the solved riddle wins.
2. Prize is the much coveted "Competition Winner" award and a massive 2+rep!
3. Staff cannot enter.
4. You can reply more than once with different suggestions.
5. Don't post the riddle if you have decoded the message.
6. The competition will not end until someone has posted the solution to the riddle.

Here's the encoded message:

n£dj$eql$tqug$u@jn$qw£n£jj£xg?q£n£dkqt%%n£jg$qg$

And here's a clue to get you started:

The code I devised is simple alphabetical replacement, (a=z, b=y), that kind of thing, but the message could have been rearranged before being put through the encrypter. Here's an additional clue, the alphabetical replacement for 'hym' = 'dlt' BUT if you put 'rythym' through the entire encryption process it comes out with 'tldjln'.

Plus, here are some more letters that I think you'll need

a - $
o - %
u - ?

GO!
