this is a perennial dilemma for us music lovers. fact is, streaming audio quality sucks. example: the online stream of my local public radio station is 48kbs! that's nasty. and with good headphones, i can tell vs when played on my radio. plus, you have to have an internet connection.
i think it is where you place your priorities and what you like to waste your time doing. for some, stamps. others, shiny objects. others like physical exertion. your music collection is like your book shelf. when i had to briefly store my books in some drawers, a writer friend of mine scoffed and said it's like putting your books in a coffin! don't get him started on ebooks.
anyone who's faced this issue surely has discovered the plethora of titles available on, say, spotify. i took five of the most obscure, widely-released albums i had, searched spotify, and they had all but one.
so you can simply get a stream going on pandora. and it's a great way to discover new stuff. but there is something very pleasant in retreating into my itunes library (mostly ripped lossless), playing a cd vinyl.
while it isn't a big issue to me, i want to highlight that when you listen to streaming music (or buying on iTunes), you're using a service... you're someone's data point, an exponent in an algorithm, and a dot on a slope of a graph that some executive is showing in a boardroom. there's no privacy, and they really don't give a **** about you (or the sound quality of their product). and if music listening is a passion, it's nice to have a little privacy.
all that said, there's a balance. and once you do get things sorted out with your library and it requires less work, it will always be there for you - whether or not you listen daily, weekly, or monthly. there are times i don't touch my music for weeks.
