I find that especially with Pink Floyd, each album is an entire work of art like a painting and I can't just pick and choose songs into a play list.
That said, I'm impressed that someone in the 10th grade would have such amazing taste in music!
I feel the same way. I will only very occasionally pick out a song from a Pink Floyd album, I'll almost always listen to it from start to end (unusual for me). With The Beatles, it's similar, but I do frequently listen to single songs. I don't usually listen to The Beatles on the go though, and prefer to listen to the records when I'm at home and it's quiet.
My dad brought me up listening to AC/DC, Queen, Led Zeppelin, Metallica, etc. All the classic rock. The first rock song I remember loving was "The Ballroom Blitz" by The Sweet. I started to branch out into more rock (alternative, progressive, punk) and metal a couple years ago, and now listen to almost anything that could be considered rock (more picky about metal). I still do and will always love classic rock, and was actually planning on listening to AC/DC on the bus and Pink Floyd during my study hall.
