I have been listening to Spotify for a couple weeks now and occasionally I will run into songs that sound like the CD skipped while it was being ripped into a file. There should be away to flag the song to for Sptify to investigate the file for problems and possible replacement. I stream while driving so a detailed problem explanation would not work for me but a quick one press flag would be awesome.

Your idea was submitted a while ago and unfortunately didn't receive the amount of kudos needed to stay active in the ideas board (100 Kudos per year).
In order to keep the Ideas Exchange clearer I'll close this idea for now, but this doesn't mean Spotify rejected this idea.
If you think this is an idea which needs to be implemented, you're welcome to post it in slightly different again :)
Have a nice day!
