are you looking for curcumaural only?
DT770 is the definitive "ghettoblaster" if you are looking for a pair of headphones with a lot of bass.
D1100-- sounds almost as good as the D2000 with the right EQ and performs very well with your genres
M50-- probably the most versatile 'phones i've ever experienced, but comfort is an issue (for me) and the soundstage is a tad bit smaller than the D1100. performs very well with almost all genres including the ones you've mentioned
cannot comment on the other two as i havent listened to them
DT770 is not pure quality when it comes to sound, but it would still sound quite satisfying for most people. Since most people don't really care about the soundquality. They are just happy as long as the bass is punchy.
You better listen to a pair of DT770 before buying it.
Go for M50 - Ultrasone 580 would be the best for trance and dance but I am not too hot on the pop.

Yesterday I was comparing the Audio Technica ATH-AD700s and the Denon 1001s and the Beyerdynamic DT 770 80-Ohm, the DT 770 are now my prefered headphones.
Here are some more reviews:

And I think if you search on here, you'll find that the M50, HFI 580 and DT 770 gets compared a lot.
