Using Feedburner to add multiple iTunes categories to my podcast?

Aware that SoundCloud does not yet have capability to add my podcast to multiple categories on iTunes.

Here I found a SoundCloud help article telling those of us that this feature is important for to use Feedburner. Got that all setup. BUT...

The article is not clear about whether we will need to change the rss feed here on SoundCloud or if somehow iTunes will magically pickup that information?!

What my guess is that we would also have to redirect our feeds?

Would you please clarify this for me?

Thanks!

Also do you know when these features might roll out?

• multiple categories for iTunes
• ability to define which episodes are explicit vs clean
• a separate description section for user profiles and podcast summary

All of the above features would make my heart sing! And I'd never jump ship for Libsyn.
