I picked two worlds. Meta & Downhome.
(I'm here also for Legends of Grimrock btw).
So, first off, I'm Italian, but i'm still hearing it fine. (no weird ports to unlock or anything) using Opera and everything went fine, the Opera browser didn't even detect the radio as a popup. Of which i'm surprised.
Though one thing would be to point out that Meta world shouldn't be suitable for minors age <13. Condoms' publicity and game babes, while perfectly fine, should still be considered rated T. The genre was clear after a while: rock of old and games of old. Coupled with *brotips* and the like. Nice but, as stated before, requiring at least a warning for minors.
(or it's me who got the short end of the stick, though i suppose the feel of Meta is about that. seeing how the newsletter was about *sex tips* and so on.)
Downhome's feel was the interesting one. I understood it was about guitars' and west, albeit seeing the Oregon trail game, I thought it should have been seen over to Metahead. you should clearly *differentiate* the worlds, so as to not have, later on, the problem of "We've got this cool track, but it could fit perfectly here, here and here".
I second the need for a timer for songs, with maybe a visible tracklist of "the next song is going to be" directly seen on the player and *not* as a click menu.
(which, btw, shows the past songs, but at least knowing one or two songs yet to come too wouldn't be bad)
Hope I was of help. And I'd second a non-english station.
