I'm running Pandora Saver 2 under WINE, following the instructions here: http://zzj.itf-inc.com/s2/docs/wineinst.html
Following the Mac instructions and using the latest version of WINE (at this time being 1.3.15) and yes, I did check "use WINE mode" in the installer.
It loads up, configures, and connects to Pandora just fine, and tells me it's running in WINE hacks mode.
It will play the music okay, but every couple songs or so, the music will just cut out mid-song. It appears to continue playing, just no audio. Checking the saved MP3 file, it seems it's affected as it will play
