Good question, while i do enjoy many styles and genres of music, the first one i bought personally would be the games documentary. and might i say what a fantastic album  it is. unfortunately my old man smashed it, i do however have it on i tunes. I listen to it from time to time, :D not really a music guy tho.

First single I ever bought was Stand and Deliver by Adam and the Ants

First album was one of the Top of the Pops compilation albums, both around 1981

First single was Bittersweet Symphony. First album was Word Gets Around. Seems my taste in music hasn’t changed since I was 13, cos I still listen to Urban Hymns and Word Gets Around from time to time.

If we're not counting stupid shit we bought at the age of eight (and we're not - my rules), then I bought Queen's "The Game" on cassette when I was about 12 years old.  After that I went bananas and starting buying a bunch of metal shit.

When I was a kid, I heard this song on the radio that went, "whatever I said, whatever I did, I didn't mean it.  I just want you back for good (want you back)."  It was a catchy tune and I had to have it on a CD to listen to on repeat, with my new anti-skip portable CD player.

Way back then, there was no Google, or any listening apps that will listen to a part of a song you want to know the title for and it finds it for you, but I remember there was some sort of device that you could scan the barcode on a CD and it would play you some samples of that CD through the headphones.  I started scanning a bunch of CDs until I scanned the first Backstreet Boys CD.  "This has to be the group that sings that song," I thought to myself.  So, I bought the CD.

When I listened to the CD, it was most definitely not the group that song the song I was thinking of, but I wasn't mad.  The Backstreet Boys had some great songs on their first CD.  

Later on down the road, I found out the song was called "Back for Good" by a group called "Take That" and it's a classic as well.  I don't know any other song by the group, so don't ask lol

Very much like a previous replier, I was also a fan of the very niche and underground group called The Backstreet Boys, or BSB for those of us truly in the know. I think their first album was the first CD I ever bought myself. The father of a girl in my class worked for the record company so was able to secure me a copy on the very cheap...at least that's what she told me. 

The first cd I bought was an Eminem cd, I had it for 2 days and my dad snapped it in half because he told me that we don't listen to that garbage in his house. I was pissed, I threw my cd player at him. 

The first CD I bought with my own money was Slipknot's Iowa. Didn't go over well with the family, but they couldn't do anything because I didn't use their money for it ha.

I don't quite remember the very 1st one. It was either a Celine Dion CD (Let's Talk about Love) or an Usher (Confessions) one. Loved both, think it was the Celine Dion one that was first.

I think I'm technically a millennial but I'll go ahead and answer anyway. The first album I ever bought was Dookie by Green Day on CD. The first LP I ever bought when I started my vinyl collection was Axe to Fall by Converge.

I didn't buy it, but the first CD I got for my birthday back in the early 2000s was guns N roses greatest hits collection. It was the gateway into rock n roll for me, previously I listened to country because that's what my dad listened to, once I got this CD everything changed for me.

First stuff if ever brought concerning music was an old Bob Marley Vinyl, never regretted it.  

Hmmm. I am pretty sure the first CD I ever bought on my own was Celine Dion's. I loved her and well I still do. I thought her music was so epic back then. Oh, it was "A New Day Has Come". Then I bought the Usher Confessions album a couple years after that. Most people probably had that one too.

I can't really recall, especially due to my time working in a store that sold a lot of music in high variety. Like I want to say the first one I ever bought was an Earth Wind and Fire best hits for my parents or something but the first I can recall buying at least is High as Hope - Florence and The Machine. I only deeply recall it because I'd recently been told about them and as I was exploring the bands discography I noticed in the coming New Arrivals would be that album.
