El rock es un género musical que tuvo sus orígenes en los Estados Unidos a mediados del siglo XX y que posteriormente se extendió por todo el mundo durante las décadas siguientes. El rock es una fusión de varios géneros musicales, incluyendo el blues, el country y el folk, entre otros.
El sonido del rock se caracteriza por el uso de guitarras eléctricas, batería y bajo, aunque también se incorporan otros instrumentos como teclados y sintetizadores. Las letras de las canciones suelen abordar temas diversos como el amor, la política, la sociedad, la rebeldía y la juventud.
A lo largo de los años, el rock ha evolucionado en una amplia variedad de subgéneros, como el rock and roll, el rock progresivo, el punk, el heavy metal, el grunge, el indie rock y muchos otros. Algunas de las bandas más influyentes en la historia del rock incluyen a The Beatles, Led Zeppelin, Pink Floyd, The Rolling Stones, Queen, Nirvana y Radiohead, entre otras.
ABBA fue un grupo sueco de música pop, integrado por Benny Andersson, Anni-Frid "Frida" Lyngstad, Björn Ulvaeus y Agnetha Fältskog. El nombre es un acrónimo formado por las primeras letras del nombre de cada miembro (Agnetha, Björn, Benny, Anni-Frid). El cuarteto se formó en Estocolmo en 1972, pero solo lograron fama internacional al triunfar en el Festival de la Canción de Eurovisión 1974. Desde entonces, ABBA ganó popularidad empleando melodías pegadizas, letras simples y su sonido propio, caracterizado por las armonías de las voces femeninas y el "wall of sound", un efecto musical creado por el productor Phil Spector. Björn y Agnetha contrajeron matrimonio meses antes de la formación del cuarteto, mientras que Benny y Frida lo hicieron en 1978; los cuatro lidiaron con sus obligaciones artísticas al mismo tiempo que se ocupaban de sus nuevas familias. Sus grabaciones tuvieron un impacto comercial que los llevó a convertirse en los artistas más exitosos de su compañí...
I got appointments, work I have to do
Keeping me so busy all the day through
They're the things that keep me from thinking of you
Ohhh baby, I miss you so, I know I'm never gonna make it
Oh, I'm so restless, I don't care what I say
And I lose my temper ten times a day
Still it's even worse when the night's on its way
It's bad, oh, so bad
Somehow I'd be doing alright if it wasn't for the nights
(If it wasn't for the nights I think that I could make it)
I'd have courage left to fight if it wasn't for the nights
(If it wasn't for the nights I think that I could take it)
How I fear the time when shadows start to fall
Sitting here alone and staring at the wall
Even I could see a light if it wasn't for the nights
(Even I could see a light I think that I could make it)
Somehow I'd be doing alright if it wasn't for the nights
(If it wasn't for the nights I think that I could take it)
No one to turn to, you know how it is
I was not prepared for something like this
Now I see them clearly, the things that I miss
Ohhh baby, I feel so bad, I know I'm never gonna make it
I got my business to help me through the day
People I must write to, bills I must pay
But everything's so different when night's on its way
It's bad, oh, so bad
Somehow I'd be doing alright if it wasn't for the nights
(If it wasn't for the nights I think that I could make it)
I'd have courage left to fight if it wasn't for the nights
(If it wasn't for the nights I think that I could take it)
How I fear the time when shadows start to fall
Sitting here alone and staring at the wall
Even I could see a light if it wasn't for the nights
(Even I could see a light I think that I could make it)
Guess my future would look bright if it wasn't for the nights
(If it wasn't for the nights I think that I could make it)
If it wasn't for the nights
(If it wasn't for the nights I think that I could take it)
if it wasn't for the nights
(If it wasn't for the nights I think that I could make it)
Even I could see a light if it wasn't for the nights
(Even I could see a light I think that I could make it)
Guess my future would look bright if it wasn't for the nights
(If it wasn't for the nights I think that I could take it)
If it wasn't for the nights
(If it wasn't for the nights I think that I could make it)
If it wasn't for the nights
(If it wasn't for the nights I think that I could take it)
Even I could see a light if it wasn't for the nights
(Even I could see a light I think that I could make it)
Guess my future would look bright if it wasn't for the nights
