Well, it's hard to choose a favourite song. And anyway, we usually classify things, but it's not always a good thing. The fact to decide : "I will take less pleasure in listening this song more than this one" is a little bit disabling.
You sometimes have to forget all of that to take more pleasure. So personally, I will just tell 5-6 songs that are a little bit higher than others in my opinion.
I think I prefer a little "The past is a grotesque animal" by Of Montreal, because even if the beat is a little bit under the others, the lyrics are the most incredible I've ever heard. Some lines are so awesome that it makes it even more transcendent than a good beat.
Then, I would say :
- Again, by Archive (Great lyrics)
- Hurt, Cover of Nine inch nails by Johnny Cash. (Great lyrics)
- Creep, by Radiohead (Great lyrics). Not because of the chorus, but because of an incredible moment, a little bit before the end, that isn't so known by the public.
- Can't stop me now, remix by The bloody betroots.
All these songs, apart from "Can't stop me now" are a combination between a great beat and great lyrics.
Finally, I will just mention some songs by dEUS. I Love them a lot, but I love this band so much, that I think my opinion is biased on that. (Just in case you want to listen to them, remember that the beggining of their songs are usually boring, but there's a nice crescendo, and their finals can be awesome).
-The magic hour (wait the final)
-Instant street (The only song that's not sad in my favourites, with "Can't stop me now")
-One advice, space (No interest if you don't listen to the lyrics).
I love Gimme the heat and Bad Timing too. (for the final.
I'm done, sorry to be so long. But now, I know what I can answer the next time someone ask me the same thing :)
