Different song playing than what I click?

[Averagebunnies]

Ive had this problem for about a week or so, whenever I click a certain song it plays something different than what I hit. It also isnt showing my songs that have numbers, but plays them if I hit the first few somgs on the list. I tested it a while ago and it plays about 12 songs up from what you click on? Also there are grey lines betweenthe letters. Like A and B have a line between, B and C, and so on
Would love some help.
