While doing homework, I tend to listen to music using Pandora or a Youtube playlist. Times have changed compared to the past when people would use an old fashioned radio or a Walkman/MP3 player. Then we have transitioned to a separate iTouch and cell phone and now it has evolved to a one-in-all touchscreen phone with apps and music as well.

Unfortunately apps tend to be full of advertisements...as do websites. Especially since they provide free services, they need to make money somehow. I can live with an ad now and then if I get free services. Still, we could get rid of the ads if we paid for a membership, but naturally if we can get something for free, we tend to.
