If you make it to heaven, and have received Jesus as your Savior and Lord, you will be spending your time praising the Master. You will not be worried about material things like high end stereos. They will all pass away. The only things that go are things eternal. Things that you cannot see with your naked eye, because they will all pass away. It is appointed man once to die, but after death the judgement. Hebrews 9:27 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. Romans 6:23.
Will there be stereos in Heaven? Cables?
Or will you just think of a song in your infinite mental list and it will start playing in your head? If so, there will likely be a way for friends to listen to (new?) songs together and surely you couldn't play it so loud in your head that it would disturb others, don't you think, but on the other hand, in Heaven, wouldn't you think that you could tell what others were thinking ,i.e. hearing, and you could change it and the 'player' would still like the song you played better? Plus if the best cable ideally is no cable will there be cables or wires in heaven,I think not, you? Thanks.
