Changing tags on actual mp3 file

[ksefteri]

Few requests.

1) Some songs that I buy online have the wrong genre. For example, Christmas music listed as miscellaneous, or soundtrack, or pop. I found out I can modify the genre tag in power amp, which is fantastic. However, it doesn't change the genre tag in the actual file. Reason that I suspect this is that when I open the song in other music players (Google, Amazon, HTC), the original genre still shows up.

It's there a way to add function of permanently changing the tags?

2) Can you add theme that has white text instead of neon\fluorescent?

Thanks for this great program, that I'm sure can only get better and of course sell more as it gets better.
