I'm not even sure if this belongs in this forum but here goes... Often I find myself wanting to purchase a song but it is listed in multiple ways. For instance, the song is available as a single, as part of an album and as part of an EP. It's the same song, same length. I want to add that in most cases I also do not care for the whole album, just a song or two. So I have gone the single route in the past. That said, there might be an advantage to getting the "version" that is part of the album somehow. Any ideas? Which of these do you usually get?
