To those who are brave enough to get the leaked version of Windows 7 Beta 1 (Build 7000), DON’T USE your Windows Media Player 12 (built-in) to play your mp3 files!
The reason is because there’s a bug that may actually corrupt your mp3 files when you set Windows Media Player to automatically retrieve media information from the internet (or when you edit your mp3 tags). As a result, a few seconds at the beginning of your song may get corrupted/truncated because of the false meta data update.
This is a confirmed bug and will be addressed by Microsoft after the Beta has been officially released to the public. I think this should teach a lesson to us not to use a leaked version ever :)
