LPs are still common with a lot of people. I buy cheap cassettes to play in my car. CDs are still common. The only things that are strange to many people are 8-track tapes and 78rpm records. I don't think there is anyone who thinks listening to albums/LPs, CDs or cassettes is bizaare, and it doesn't really show any ones age in a negative way. When internet speeds soar beyond our imagination and 24 bit FLAC is the standard digital music file, will people say "remember mp3s? lolz"
