RE: As Chalky mentioned earlier, you can sit down for a little longer whilst listening to them at home.
..... I've got about 15,000 x soul / gospel / blues 45's ... but when at home, I put LP's or CD's on the stereo system & I can then get on with something else (posting here for instance).
If I decide to play some 45's, then I have to stand next to the deck which is OK for 15 to 20 mins but then gets tiring -- no room for a comfy chair in the record room & the bed is always covered in records, books, mags, CD's, etc (you may have already guessed that I don't like tidying up & 'putting away').
