For me, whether or not I like a song can depend on the "message" of the song too. But oddly enough, sometimes not. This can happen if I really can't understand the lyrics and the sounds are just amazing to me.
For example, I'm listening to "This is War" by 30 Seconds to Mars, and I think it's an amazing song. I feel this..."buildup" throughout the song, and it reminds me of all the things that I think are worth fighting for. Towards the end it hits its high mark and I feel like I've just won against all odds. But I'm a sucker for things like epic battles with good vs evil and things that have this message of "put yourself between danger and those you love", if you get my drift. Not sure I explained that well enough but oh well lol.
