Just to let you guys know, an employee from Google has closed the bug report for the aac+ decoding issue where Pandora, Slacker, etc. sound terrible in Froyo with Stagefright enabled:
Issue 9308 - android - eaac+ and aac+ decoding sound quality problems (Android 2.2) - Project Hosting on Google Code
@ Sapphire devs: will you be able to incorporate the fix (see the very bottom post) referenced there into the next Sapphire release, please? I think many Droid users would be very happy about this, seeing as the source appears to be available for the fix!
