Do you look up all the songs by an artists you like and download the one's you like. Meaning if I like a few songs by Tamar Braxton I look up all her other songs and download the songs I like by her. Or do you just download the songs you come across, or another way?The issue is if I do the first option I will not have enough storage space on my iPod. Which method do you use? Or do you use a different method?
