LOL I remember when there was no better alternative to buying shitloads of CDs. In some ways I miss the relationship I had with music back then. My sister beat the shit out of me one time for sneaking in her room to copy a bunch of her CDs. Made a big song and dance about the ethics of music piracy!
In that scenario though, your best bet would be to buy more than one CD, rip them to a computer with a USB optical drive, and make yourself playlists that are 8 hours long. I certainly would never advocate downloading music with filesharing software like soulseek.
