How the HELL do I use IPhone spotify?

I just got it yesterday and have no idea how to use it. When I search up ONE song, the WHOLE freaking album comes on and I only wanted ONE song. When I 'star' a song, the whole album comes along too! For example I was searching up "counting stars" by imagine dragons and the whole album showed up and I had to wait until the freaking song came on! Then I 'starred' it and it came with the stupid album! I'm only asking for this:
1- how do you search and get ONLY the song you're looking for?
2- How do you add ONLY THE SONG YOU WANT to a playlist (I made my own)?
3- how on earth of you only get the song you wanted, added to your playlist WITHOUT THE WHOLE ALBUM?!

Will an unlocked Sony Xperia Z2 run on AT&T in the US?

I'm looking at buying an unlocked Sony Xperia Z2 to replace my current Iphone 4S. I was wondering if doing so would cause any complications, mainly because Sony hasn't released phones for US AT&T users. If I buy this phone internationally unlocked, will I be able to move my Iphone 4S sim card into it? Will the phone run AT&T coverage, particularly 4G LTE?
