Ok, so it may be a bit of a noob question, but how many of you use your Droid as a MP3 player? Recently, my stereo and iPod were stolen out of my truck, and now I don't have any type of MP3 player. I only really listen to songs while I am riding my Harley. I almost bought a 64G iPod touch tonight, but found a 32B micro SD for about a 3rd of the price. I figure if I can stick half my songs on that 32G card then whenever I do ride, I can swap SD cards and have most of my good songs to listen to, along with Pandora, when I have service. So how many of you use the Droid as a MP3 player and how long does your battery usually last?
