It's finally out of beta, it's a little bloated, it broke my plugins (Messenger Plus! and NG StuffPlug), but after downloading the latest versions I've got it pretty much back to where I was with 6.2.
One of the new features (or bloat) is the ability to show what song you're listening to on Windows Media Player (and iTunes, which surprised me). But I use Winamp 5 (it's small, quick, simple)! There used to be plugins that'd change your MSN name to show the song, so I assumed I could find a plugin that'd show the song from Winamp in the new box in MSN7. I was happy to find Toaster
and it works fine with Winamp 5 (you can also get the MSN Messenger Status Plugin from here, a plugin for Winamp 2.x users). It does lots of other things I haven't played with yet, as I loaded the MSN Only profile. Now my only gripe is that MSN7 shows "Title - Artist" when all sane people use "Artist - Title" - you can switch it over with a patch, and Toaster would let me switch it over manually, but then you'd never find the track on MSN's music store (not that I particularly care).
Also, I managed to buy Beth Orton's last album (the 2CD version) for a superb ?4.99 from 101cd.com (along with several others cheap CDs, I even found Prodigy's last album for ?3.99 - it's not amazing, but at that price it's worth it).
