My wife & I bought an ipod a year ago. She swore she'd never use it b/c she couldn't figure out how to put music on it. I showed her how, & I haven't seen it since.
I discovered a good radio station in the DFW area 89.7 power fm. It plays good HARD Christian rock.
When I walk outside in the morning (my favorite time of day to walk, if I can get out of bed :) ), I like to listen to upbeat praise music. My church Gateway Church in Southlake, Texas, has some great CDs. I find them very motivational and encouraging and they just get my mind on the right course for the day. When I lift weights with my husband (and sometimes when I walk), I like TobyMac. His album Portable Sounds has some great music on it--upbeat and positive.
I love to listen to TFK (through up your rawk fist), RED, and lately Toby Mac. The entire Portable Sounds CD is awesome to listen to anytime and there are about 4 soungs that will just get you up and moving.
