So first let me start off by saying my X is awesome and this is the only weird issue. Whenever I seem to play music (I have maybe 1,000 songs on my 8gb sd card) my phone likes to randomly reboot itself, or the music app freezes it happens atleast once while im at the gym so....id say it on average should happen once every 2.5 hours of music play. What could be causing this should I download a music app from the market or just deal with it cause it gets very frustrating my phone completely locked on the DROID eye screen during a random reboot yesterday and I had to do a battery pull. Any and all help is appreciated thanks!
Try clearing the data/cache for the music app. Menu >settings >applications >manage applications >press the "all" tab at the top >scroll down to Music >press on it and select clear data.
