I just bought Tal Ben Ari's Sheelá on MP3 from Amazon. I've been buying most of my music lately from the Google Play Store, but strongly dislike the limited number of downloads they allow a purchaser. Purchasers do buy the MP3s, right? And, no, I don't care about any fine print since the e-mail receipt which Google sends clearly states that the track is purchased. Quote: You've purchased a track on Google Play.
The reason I switched to Google from Amazon was that Amazon no longer supports Linux, and forces Linux customers to download songs one at a time. PITA for albums.
So I can purchase the MP3s from Amazon and then download them to my Android. I probably want them there anyhow, and, of course, backed up in the cloud. Then I can sftp them to my desktop machine. Amazon doesn't get in the way, and the Google bean counters don't get involved.
An issue that may have me reconsidering the above is that Google says they have Tal Ben Ari's Sheelá at 320 kb/s, whereas the Amazon MP3s vary from 203 kb/s to 230 kb/s.
Note to Android users: AndFTP is a wonderful app, allowing me to connect to my desktop at home and a server at work wirelessly.
