Now, yes, I know, downloading music or duplicating CDs is illegal.
However, I overheard someone talking about the matter.
Assume I bought the album ABC with the songs A through Z from a store (i.e. I don't have digital copies like when you buy music CDs from Amazon). Then, I lose the CD.
Am I allowed to get the songs (and only the songs from the album ABC) from, say, YouTube and download them if I can prove that I previously bought them (i.e. the receipt)?
Edit: I'm living in Germany.
