This is the same song, mastered at four different dates.
Don't we see a horrible trend going on here?
No, this isn't technology getting better, enabling us to record at louder deciBel levels. This is modern times demanding that songs be pushed to the brink of a recording, making all sounds as loud as the other. There are no soft sounds and loud sounds, there is just the song compressed to hell, giving no dynamic range.
Go ahead, test it out. Put on any song released in 2008. ANY song. Listen to it.
[Note: for an added effect, choose a strong rock song.]
Now go listen to something released in the 80's. Pop in Piano Man by Billy Joel. Take a ride with an original recording of Bohemian Rhapsody.
Now, notice the difference.
