Partial songs on YouTube is alright for promotion (but still a violation of their TOS). Maybe just half the song. If they were partial songs that linked to the band on iTunes, the official website, also disabled comments and directed people to the official forum and mailing list, etc, then I would have no complaints. The problem is people upload full songs and then use it like a radio, they don't link to official sites or places to buy the music, and the bands suffer.

About fan support to radio and magazines, etc- it's about creating awareness. If magazines and radio kept getting requests for a particular band, eventually they may take notice. But it actually does work, too, providing enough people do this. The problem is people don't act in any way.
