MP3 scratching/crackling sound

As of 3/12/18 I am using the newest version of Mac OS and the latest version of iTunes, along with the newest version of IOS

About a week ago I noticed a few of my MP3 tracks starting having a scratching/crackling in sections with a lot of bass and reverb. Naturally I figured my car speakers were blown, but I hear the same thing through my Bose Blutooth headphones and my Bose Speaker. The tracks sound fine and normal when I listen to them through my MacBook (where the tracks originate from) both through the laptop speakers and through my bluetooth headphone.

Could there be a corruption with the MP3 track that would cause the tracks to sound that way? Some of the tracks were downloaded from amazon, others were ripped from CDs back in 2006. It seems to be an issue of music that is played through my iPhone.

Any help would be amazing
