I like CD's over MP3's, but I love the MP3 format too because of its flexibility and portability. I have a philosophy, if the CD is good enough (meaning 4-5 songs are great), I buy it. If I only like one or two songs, I try to find them as part of a compilation, soundtrack, etc. If I can't find them, I try to get it from a friend.
I don't like to buy music from an online service. It's not that I refuse to pay, but that I don't like the quality that's available.
When I rip MP3, I use settings and bit rates that are not usually available from online services. Sometimes I encode at 192 Kbps CBR, 224 Kbps CBR, or 224 Kbps VBR. It all depends on the type of song and purpose. As you can see, my settings are way better than the 128 kbps AAC, WMA, MP3, etc that are "standard" for online music. I'm not an audiophile, but I consider myself an above average listener. I often notice the difference between a 128 Kbps MP3 file and a 192 Kbps one. Bottom line there's nothing out there that would make me wanna buy an MP3 song.
How do you acquire most of your MP3s?
From an online subscription service (which one?)
From a pay-per-download service (which one?)
From a P2P client (is it legal?)

I don't have MP3s (why not?)
