Hi! I neeeeed help!! I can't seem to use a computer which I know has played sinful music,
I don't believe any music is sinful.
The words may be dodgy/unpleasant, but it seems you didn't write them.
has had sinful content shown on it even accidentally.
A computer is a thing.
It cannot be contaminated by "sinful content" nor can you be defiled because if it. Just as if you went to a charity shop and bought a jacket that had been worn to commit a crime, you would not a sinner.
I know the computer is a tool which can be used for good and bad, but I don't want to use an object which may have been affected because of the sinful content it has appeared on it..
It can't be affected.
The only people who can be affected by "sinful content" on a computer are those who put it there, or those who watch it.
Although news items could come into that category - reports of war, abuse, telling lies etc. Where would you draw the line?
..unless it is The Bible which offers correction on such topics.
Yes, but the Bible includes sinful behaviour - murder, rape, war, attacking others etc. Are you going to stop reading it?
I don't want to think I'm being an accomplice for using a tool which already has possibly had content show up that was offensive to God.
You won't be.
This also applies to real life ... Can a place where there was possibly blasphemic music towards God like a market be a place for a Christian not to CONSUME from, make business with etc? or a clothing store etc?
No.
Sorry, but if you are saying that you are not going to buy from a shop which once played/sold, blasphemous songs; never go to restaurants because cult members/ devil worshippers may have gone there, or buy a car because it may have been used in a crime - either you will never do/buy/eat anything, or you will go mad trying to check the history of every place that you come into contact with.
One thing is to consume from a market where meat was offered to idols who are not even real,
But to people who worshipped those gods the idols were real.
And Paul said that it's ok to eat meat that may have been offered to those idols.
but I feel like it's a totally different topic to go to a market where the ambiance is putting music with possibly blasphemic lyrics... is the place a safe place to go/is it affected even after it no longer plays such music?
Unless it is playing songs with blasphemous lyrics ALL the time, and unless you are spending hours in that place, listening to the lyrics and starting to believe them, it's not an issue.
I can't even use a computer to do my work, use my phone to text back somebody or go to a market/store where, unless I'm unaware of what happened before.
It sounds like you have a problem with anxiety.
Computers/phones are a tool. We can use them for good; to phone people, cheer them up, cause them to feel less lonely, tell them you love them. Or we can use them for ill; to indulge in unkind gossip, tell lies or plan a crime.
Even if you used your phone to do one of the latter and then sold it the next day, whoever bought it would not be "contaminated" by your sin. (Unless you had left a load of details on there etc.)
If you bought a house and later discovered that, years before, someone who hated and blasphemed God had lived there - that would not lead to you being punished.
If you believe it would, and cannot shake that feeling; simply pray and dedicate all new things - phones, computers, cars etc etc - to God. Jesus told us to pray "deliver us from evil".
Moses' staff was once turned into a snake, and was also used to perform many miracles. It had not been contaminated by having been a snake.
Jesus used Peter's boat to sit in to teach the crowds. Who knows what, or who, had been in that boat before Jesus came along? It didn't stop him from using it.
Jesus was crucified. We don't know, but it's possible that murderers, Romans or Jews had been crucified on the same cross as he was - that didn't make him a criminal.
