The phone is branded (Movistar, a phone company in Spain), and it has R6BC002 because I didn't want to put the newest firmware (because of the green Walkman light problem).

The theme i'm using is WalkmanOrange1, which I think is flash, but I'm not sure. I edited it with Themes Creator, but I only changed the lights option, choosing white as the colour. It's weird it initially shows white light and then quickly becomes blue again.

In this review, they talk about the track-order question. I can't believe it didn't happen to more people:

Electronista | Review: Sony-Ericsson W580i Walkman phone (Rogers)

This is the paragraph where they describe the problem:

One glaring omission, however, may ruin the experience for those who like to listen for the entire stretch of an album. It's the track order. For some reason, the Walkman interface simply refuses to obey the track numbering in the ID3 tags of a given song and will list your songs only by their copy order. Not only does this jumble tracks and hurt albums with continuous mixes such as the Beatles' Abbey Road or DJ sets, but even Sony's own software won't do this properly with our existing catalog. The only solution was to manually drag files over a song at a time, which isn't really an effective solution for a phone that can potentially store hundreds of songs. While we didn't consider this fatal to our experience, it's frustrating to need this level of micro-management.

Thanks in advance.
