How to clear someone someone else's iCloud info off my Iphone 5?

I got a used iPhone but the previous owner didn't wipe the phone and it still has all of his data on it. When I try to log off his iCloud or reset the phone it asks for his iCloud password. Is there a way to do this without his password? It's my brother's boss's old phone so I feel a little weird asking for his password.

Iphone deleted all my music?

I recently updated my iPhone 5s to iOS 8.4. Last night, i synced my iPhone to my iMac iTunes library and copied all of the music on there to my iPhone. Everything was fine until this morning when I looked and discovered that all the music from my phone had been deleted, including the purchased tracks. I rebooted, nothing came back. I took a look at the storage manager in my phone and about 7 GB of memory was missing ( it said i had used 11 GB, but when i added all of the amounts of storage it listed below, it only added to about 4.5 GB). I know that my music used to occupy the most amount of storage on my phone, so I think it is still there. I can't plug it into my computer for a few days. Has this happened to anyone else? Please answer this!

Can i avoid paying the $12.99 fee for Spotify on my iphone?

I signed up for my original spotify account with an in-app purchase from my iPhone using facebook to log in i'm still on the free trial but apple charges a fee so you pay $12.99 a month. NOW spoitfy has this 3-month 0.99 trial and a $9.99 membership and i want in! So i created an account directly with spotify. I unsubscribed from the spotify itunes account BUT i'm worried that if i log into the account on my iphone app it will charge me the apple price. How does it work?
