Android : Good Droid Music Phone

I'm looking for a good Android phone (other than the Samsung Galaxy S) that is good on the music front. I'm looking for something that has the following features:

1. the ability to edit/make a playlist on-the-fly (without the use of a software)

2. have the ability to add songs to the playlist on-the-fly

4. the ability to customise the EQ settings on ALL or a particular song to my liking.

5. some form of surround/3D/propreitory sound enhancing feature

6. one that supports most audio formats (like WMA, MP3 and Flac)

my budget is between �150 to �250 region.
