My current way is:
* bandcamp.com for some artists
* buying used CDs from a online music CD reseller and ripping them
* download a few from youtube via youtube-dl or something
Now a few of those from youtube are great, i'd like to buy now the album. bandcamp.com doesn't offer it and it is too specific/too new to get a used CD.
i could buy them from apple Itunes since it is rather cheap and it offers a DRM free download option (i think), but i'd like to avoid apple and its walled garden and bad user interface for linux people.
