It's impossible to say which is the best because different people have different needs and budgets. It all depends on what you want to use the phone for.
Look at the specifications of each one and decide which suits your needs and budget the best.

That's only because you are using the "come with music" service that follows strict DRM rules. It's not a fault of the phone.
Music from many other sources don't have the strict protection like this so you can do whatever you want with them.
From music part, I would go-choose-pick the N97 Mini, the N97 has very very good sound quality among other Nokia handset devices. Have not been to Nokia Forum (www.forum.nokia.com), just go there, they nicely redesigned the forum, you can compare the above mentioned phones there.
Also qwerty is an important factor here, again, if you want qwerty you gotta get N97 Mini. It is sleek, stylish, kind of Mini than it's Big bro (and most probably with less bugs too).
Design wise: N97 Mini>5530 XM> 5800 XM>5230 XM
Music Quality Wise: N97 Mini, and the rests are almost the same.
To me, music and design plays very important driving factors about the models you mentioned, also best if you got to a near retailer take a close among 'em.
"tell me which is the best, the worst, the second and the third. "
Depends on ones needs..like for me I don't need GPS or 3G..so my best pic would be 5530 with kinetic scrolling, sleek design and pocket size (not bulky) and more enhanced homescreen, plus cheaper.
