With Spotify, for $10/month, I can listen to every new album that comes out every week, plus every album released over the last 70+ years. Don't limit yourself to two albums a month. Listen to every album you have any even slight inclination to hear. It's all available. (Obviously there are some albums that are not available, but it's a small list and it's shrinking all the time).

And, no ripping required. It's all already there.

And, no problem with choosing what to buy, so no "mistakes."
