You're using the forum fine.
As for the music, install
media.Re.Scan and run it, and see if that helps. Or just restart the phone (which does a media rescan).
Also check the player - some players only recognize songs in their own folder, but some, in their Settings, can be set to look somewhere else. (There's no "stock .mp3 player - each phone manufacturer uses the one they prefer. The "default" app on my phone is called "Music", and it finds files in the SD card in the /mp3/Music folder. [Or, rather, the media scanner finds them - the app plays any music files that the media scanner - by restarting or by running media.Re.Scan - finds.])
