Reasons to use Windows Media Player to import MP3

[Exploited]

You will have many advantages that way - first of all the "Sync" in WMP will sort your music and you will be able to read the artists sorted by name in the standard player.

Second (more important) is that your battery life may increase! That's strange right? Well it turns out that if the MP3s are uploaded raw then the phone will try to read the tags himself in background. It looks like it takes a lot of time to do that and for the first few days you will notice a major decrease in your battery life. If you import via WMP - all tags are coming in the db automatically.
