There are a lot of songs that get stuck in my head. I really like music. I should really buy a microphone sometime and get around to creating my own music!
Here are some of my favorite songs at the moment.
"Tom's Diner", by Michigan & Smiley
http://www.youtube.com/watch?v=FN0lyPl4kYkThis song has really, really good bass if your speakers or headphones can go that low.
"Game Time", by Zomboy
http://www.youtube.com/watch?v=aZnMb93C0OgEnergetic dubstep sounding music.
"Revolution", by Kirk Franklin
http://www.youtube.com/watch?v=jr41skFqzb81990's Gospel rap music.
"Through the Fire and Flames", by Dragonforce
http://www.youtube.com/watch?v=0jgrCKhxE1sFast "epic" sounding power metal music.
"Ojos Asi", by Shakira
http://www.youtube.com/watch?v=5BzkbSq7pwwSpanish dance music, kind of reminds me of belly dancing music.
"Chrome Lion", by Unicorn Kid
http://www.youtube.com/watch?v=DsqZ27-k4UYKind of sounds like retro video game music. I like the Beat Hazard remix, too.
"Six Weeks", by Of Monsters and Men
http://www.youtube.com/watch?v=SBtnnZX_jDUMellow, catchy alternative music.
I don't know about catchiest… but each time I hear it, the song Animale tends to get stuck in my head for a day or two.
Animale, by Don Diablo, featuring Dragonette.
I like that "Animale" song, by Don Diablo. Here's another song that features Dragonette, "Big in Japan".
