Shoutcast stations cannot be reproduced

There seems to be a problem with playing streams from Shoutcast servers in the browser; see for example:

In Radiolise, such streams cannot be reproduced even when using the workaround of appending a semicolon. These are a couple of stations that are affected by the issue:

Postrocks.me Radio - Space Gaze http://postrocks.me:8000/;

Aural Moon: The Net's Progressive Rock Garden http://live.str3am.com:2010/;

They are both in the radio-browser.info database; they play in the RadioDroid app.
