iPhone Music Stuck on White Screen

This was the best and easiest solution when my iPhone Music app was stuck on a white screen:

1. Double click on the Home button
2. Swipe all the app screens upwards one by one until only the home screen is left
3. Click on the Home button
4. Press and hold the Sleep / Wake button until the screen shows something like "Swipe to turn off"
5. After 30 seconds or so, press and hold the Sleep / Wake button to restart the iPhone."

Stop ads from following you around the internet

Stop ads from following you around the internet. Sometimes I've already bought the product so it's even more annoying. AKA Remarking, Retargeting, Online Behavior advertising,

I just opted out of a big one here. So many flashing ads. So annoying: http://www.criteo.com/privacy/

Update 10/15/2016: Another opt out. This one will stop your Amazon viewing from following you around the internet: https://www.amazon.com/adprefs/ref=dra_a_ms_hp_hn_xx_P3378_100

Update 10/24/2016: Another site to set opt-out preferences (it just set 106 opt-outs for me today): http://www.aboutads.info/choices/
