Oh God! I love that song. My type of music is actually rap/electro pop but an Adele song? That better be on my iPod the moment it's released
Dude, I agree with you... I know that Adele is on the best singers in the world, but her music genre is pop, not a relaxing music as you say. If you like to listen a relaxing music, then I will suggest you something like: Above and Beyond, Blank and Jones or Schiller.
I find that piano and violin instrumentals really calm me. My favorite musicians are The Piano Guys, and I'm an avid fan of their original compositions too! I also like piano pieces by Yiruma and Bach.
