The October issue of Blender magazine (search), on newsstands Tuesday, lists "The 500 Greatest Songs Since You Were Born," (search) which, for their readers, means the best songs since 1980.

No. 1 is "Billie Jean" by Michael Jackson.

Twenty-five of the Top 50 are rap songs.

"We just wanted to give people some new juice for their iPod," said Blender Editor-in-Chief Craig Marx. "They're all really good songs."

Marvin Gaye's "Sexual Healing" is No. 45, but Britney Spears' "... Baby One More Time" is in the Top 10.

"Sampling a loop, like it or not, is what's considered great, vibrant music these days," said Marx.

"For Blender, what makes a song a great song doesn't have a lot to do with the level of musicianship," Marx added.

Blender's top 10 choices are:

1. "Billie Jean," Michael Jackson

2. "B.O.B.," Outkast

3. "Sweet Child O' Mine," Guns N' Roses

4. "One," U2

5. "Smells Like Teen Spirit," Nirvana

6. "Like a Prayer," Madonna

7. "Love Will Tear Us Apart," Joy Division
