MINIMAL  Unfortunately Pandora removed those features from their Mini Player. As a workaround you can login to Pandora through Safari and it will hold onto your login credentials in PandoraMan.  
(Version 1.0.17)

PETIEG  Does what it says and more... like pop up ad's in a browser. Two as a matter of fact... not worth it IMHO.   
(Version 1.0.17)

MACUPDATE ADMIN  But to whom and what are you responding?   
(Version 1.0.14)

MINIMAL  To the comment regarding about ads not loading correctly.  
(Version 1.0.14)

MINIMAL  Too bad MacUpdate doesn't let you update your comments... damn typo's =P  
(Version 1.0.14)

MACUPDATE ADMIN  OK, but if we allowed users to edit their comments, then they could edit out whatever parts of their comments that may have become inconvenient sometime after posting them, say, when and if someone took issue with their post and responded to it, and then edit their original post and claim they never said (posted) any such thing. After years of experience with 'boards', I've seen just this sort of thing happen.  
(Version 1.0.14)

SHOCK J  I've seen forums/boards where the user has a fixed amount of time to update a post, say 15-30 minutes. After that it becomes locked. That seems like a good intermediate solution. If a person makes a typo they didn't see on the initial post, they can go back and fix it within the specified time frame. Locking it quickly afterwards prevents them from doing want you state, changing their comment based on a reply.  
(Version 1.0.16)

MIKELITE  i wrote to them too, a while back, and they finally got back to me about the new release. good kids.  
(Version 1.0.12)

RICH88  When I wrote Pandora.com about the problem of PandoraMan opening browser pages upon almost any action, this is the reply I received:

" PandoraMan is an unauthorized, unsupported program. The only way to use Pandora without seeing our full range of ads-- while staying within our Terms of Use and still helping us keep Pandora a sustainable service-- is to subscribe to Pandora, and continue to visit http://www.pandora.com directly. [What you describe are bugs and glitches within that unsupported program.]"  
(Version 1.0.12)

MIKELITE  same here. pandora must've changed their streaming somehow because even when I use it on their site it refuses to play continuously in the background unless I go back to (see the ads) player. Gotta pay the bills I guess.   
(Version 1.0.10)

MINIMAL  They are Pandora's ad's and go directly to them.  
(Version 1.0.8)

MINIMAL  I know people are worried about the advertisements however these are required for Pandora to pay the large number of musicians they keep on staff. As long as I work on PandoraMan it will be functionally identical to the Pandora Mini Player.

If you don't like the Ads the way they are you should contact Pandora and tell them. As for the growl support, it is not functional because Pandora no longer provides the Artist and Track information due to stream rippers abusing that privilege. Unless they give me access to their API this feature will remain broken.  
(Version 1.0.7)

SCHMELDING  Well, that's a big poo. Oh well.  
(Version 1.0.7)

JOSHUA7  Without those ads they wouldn't have any way to license the ton of tunes they have. If you like it, support it by getting a subscription. $36 for a whole year is really worth it to keep the project going.

From the Pandora FAQ:

Pandora is available in two forms. Both versions have exactly the same features.

The first form is an advertising-supported version which is entirely free. Over time we'll be incorporating ads into this version of Pandora.

For those who want to steer clear of advertising, subscriptions are available in two different flavors:

ANNUAL: 12 months of unlimited use for $36

QUARTERLY: 3 months of unlimited use for $12  
(Version 1.0.8)

BADGERB.  PandoraMan 1.0.7, which works again, has just been released :-)  
(Version 1.0.7)
