Sorry Ezequiel, if you expected to receive only one band or musician per forum user, you are wrong!
It's simply impossible to choose one, as you can see.
I'll add some of my favorite's bands, some from USA, others from Brittain, and some others from Latin America and Spain. Let's see...
Queen (Bohemian Rhapsody, We are the Champions, Another One Bites the Dust...)
The Police (Every Breath you Take, De do do do, de da da da...)
The Eagles (Hotel California, The New Kid in Town, Seven Bridges Road...)
The Beatles (all the songs!)
Maná (Reloj cucú, Vivir sin aire)
Hombres G (almost all!)
Enanitos verdes (La muralla)
Oh! I forgot Journey (Faithfully, Open Arms)
