Right now, when I press the button on my headphones, the stock music app plays/pauses. Double-click dials voicemail, rather than skipping to the next song. Is there any way to fix this? I tried TuneWiki, which is nice, but it crashed on me a couple of times. It behaves properly, but I'd obviously like it to keep playing. I realize I might be nit-picking with this one, but I screwed up my shoulder and will be in a sling riding the metro to work tomorrow. I'd like to keep the music playing and be able to change tracks using my one good hand, especially since it's likely that I'll be standing up.
