I realize I have trash taste in music, but I am proud of it, so lol.
Born This Way- Lady Gaga: I'm a pop music fan through and through, and this album has such a fun blend of genre's and pieces and just flawless instrumentals and fun hooks. Dirty gritty songs like Scheiße to fun heartfelt sax solos in Edge of Glory.
Heart Station- Utada Hikaru: Another pop masterpiece, for me. I don't understand Japanese, but something about nearly everysong makes me love it and appreciate it all the more.
Warrior- Ke$ha: the best bubblegum pop for me. Tons of fun little lyrics, good jams, and just plain smile inducing.
Kingdom Hearts1-2 OST- Yoko Shimomura: the perfect marriage of classic disney songs and Final fantasy esque OST's, addicting little melodies and emotion inducing background songs. Best video game ost ever.
And not really sure for number 5.
