Ligamusic.com is a music dowload service like iTunes Music Store, but it’s a subscription service. If you like discovering new music, and you like having files that you can keep forever, burn to audio CD, and listen in your iPod or any other MP3 player, you’ll like the fact that with you get regular, DRM-free high-quality MP3 files (192Kbps+ VBR, LAME -alt-preset-standard) without any DRM copying restrictions or "authorizing" nonsense.
Even though iTunes is now offering a selection of DRM-free files, with the files are standard MP3s and so they will work in all MP3 players, not just iPods. The main difference between and iTunes is that there is no major label music on.
So you won’t find any of the latest pop/rock hits, and only a tiny fraction of the major hits of the past. If you just want songs you are familiar with, is not the best choice.
However, if you like to have a source for a wide variety of independent-label music at great prices, you should consider it. Ligamusic does have a lot of
music: 2 million+ tracks from 9000+ labels. And amazingly, a lot of the music on
Ligamusic is also on iTunes! So people are out there just using iTunes are
paying $1 per track (or being forced to buy the whole album) for the exact same
songs, because they don’t know about Ligamusic. Ligamusic probably doesn’t have
a lot that’s not already on iTunes, but the price makes it much cheaper to
experiment and try out new things.
