1. easier to preview tracks online rather than drive to the store and wait for an open listening station
2. running out of storage space for all the CDs I bought just for 1 or 2 tracks each
3. I never know what the store has in stock and what they don't and it's a pain to try and find specific CDs in some of these places where their alphabetical tabs have all been moved around out of order
4. expensive ~ I pay less $ for each track online, and don't have to pay for the tracks I don't want. I'm tired of spending $15-20 bucks for a 10-12 song disc with maybe 2 or 3 tracks that I actually like.
5. It just saves time and it's so much easier. Plain and simple.
6. Car listening. Whether you're using a 1 disc player or a 10-disc CD changer in the car, you know what I mean when I say that it's far better to have compilation discs loaded in with songs you like on them. Having a car filled with CDs that you have to change over frequently is a hassle (and sometimes a hazard)

So, I’ve finally come to the point where music shopping online is preferable than to physically go to the store. I'm curious to know how many other people are following this trend now, and what service has been the best for you. I don't use the file-sharing services, primarily because they're illegal and artists get cheated out of any share. I'm talking soley about the subscription-based ones.
