Hi! I found this blog post which might be helpful: http://www.grammarphobia.com/blog/2011/12/especially.html I think we usually put "especially" before what it modifies, which is not necessarily the verb. In your first example, "especially" goes before "love" because those are the songs that you love the most out of the soundtrack. Your emphasis is on your preferences. In your second example, "especially" would go after "Song Gang-Ho" because he, out of all of the other actors, gave the best performance. Your emphasis, in this example, is on Song Gang-Ho giving a better performance than the other actors. You can switch these around, as well! If you want to say that these three songs fit the movie, you could say: "These three songs especially fit the movie." This would put emphasis on the way the songs function in the movie. If you want to say that you particularly loved Song Gang-Ho, you could say: "I especially loved Song Gang-Ho in his role in the movie." This puts emphasis on your feelings about the actor. It all depends on what you want to put emphasis on! I hope that makes sense! :)

"especially" usually looks best before the main verb or at the front of a dependent clause e.g I especially like olives I like olives, especially when I go out for a meal
