While I would like Notre Dame to be more welcoming to its LGBT community, it is a private Catholic school well within its rights to comply with official Catholic theology. It's truly unfortunate because many LGBT people are devout Catholics.
In addition to the issue of compensation for the artists, when you download you lose 90% of the music quality because of compression. If you don't care about how your music sounds, go ahead & download. I buy most of my music CDs at 2 brick and mortar stores that I access by taking public transit part of the way and walking the rest of the way. I also buy much of this music as used CDs, and when I'm tired of them, I give them to my local public library so that others can enjoy great music.
