Is it possible to hear a song differently after listening to it for years?

Last night I fell asleep listening to one of my favorite songs "Don't Let Me Fall" by B.o.B. In my Apple iPhone 5 earphones. I woke up and the song was way different. The quality of the song had changed even though it was the highest quality possible, and I could hear certain sounds and parts of the song differently then i could previously, but the song sounds like trash now. I thought maybe the headphones weren't plugged in all the way but they were, so then maybe I thought they were just shorting out. So I turned on another song and it was completely normal. I thought maybe it was a fluke in the file but then I went on my sisters phone and looked it up on YouTube and it was just the same as this morning! I have listened to this song ever since it's release about 4 years ago, and now it's completely different. What is going on?! This is really freaking me out! Someone please help me, I think I'm going crazy or something.

I purchased an iphone 5s from t-mobile from a guy from craigslist?

So basically after about four months of using my iphone 5s without no problems at all, I wake up one day and it says no servive. So I go to T-Mobile and they said it was reported stolen. So what are my options? Don't say sell it because I don't want to scam other people. Can I have it unlocked and use it on another carrier?

Can you pair an apple tv with a replacement apple remote?

We lost our apple tv remote months ago, due to its tiny size. The "remote" app on the iphone worked fine until the internet was slow one day. I was planning on disconnecting and reconnecting like I normally do, but after I disconnected, I no longer had control of the screen. If I go to the apple store and spend $20 on a new remote, will it connect or am I out of luck?
