So, if you were wondering what is the "ABBA band?" is all about, I can elaborate it before I start my story.
ABBA was a Swedish-Norwegian Eurovision Song Contest-winning pop music group active between 1972 and 1982. The band comprises Benny Andersson( Sweden ), Björn Ulvaeus ( Sweden ), Anni-Frid Lyngstad ( Norway ), and Agnetha Fältskog (Sweden). They topped the charts worldwide from the mid-1970s to the early 1980s. The name "ABBA" is an acronym formed from the first letters of each of the group member's given name (Agnetha, Björn, Benny, Anni-Frid). If you want to know more about the band, you can google it.
So, time for my story now. In August (I've forgotten the date), I wanted some new songs to entertain me. I was bored with all the old songs I had. So, before I start searching for new/old songs, I was thinking about what kind of songs that I wanted. Since I have been listening to metal, and rock songs for a long time, I thought it would be great if I change to other type of songs. While I was thinking, I remembered a day when I went to the theater to watch a movie, I saw an advertisement for an upcoming movie called "Mamma Mia"(I think that's the name). If you were wondering what kind of song can I get from this advertisement, well, it's pretty obvious, the title is the song! Now back to the story. So, I've remembered that song, and I started to search for that song. While I was searching, I saw a band called "ABBA", and I started to download it. Once the download was completed, I listened to that song for all night. I enjoyed the song so much and started to download more songs from this band. Even though I don't know much about this band, I enjoyed listening to the songs.
