Rhapsody - the first streaming music service. They've been around doing this for over 10 years now. I still have my log in there. Want an app for the iPad - well, it's still "coming soon". Why? Because they are slow, slow, slow, slower and slowest to update and bring their service current than one can imagine. They are and always have been a Windows focused company and Mac users are 2nd class citizens. They still do not have an app for Mac users. Over 10 years... what planet are these people on? It's always had me shaking my head. I can't recommend them to anyone unless you just happen to own devices which makes them your best choice.
Would say the current leaders are Spotify and Rdio -
comparison and you can probably find more.
Are any of these services worth it? In the old days, yes, before any of these new fangled devices we have today that let you carry entire collections around with you... I had a vinyl LP collection of over 7,000 albums. My estimated cash outlay - somewhere between $45,000 and $50,000 - would have been more like $80,000 if all those had been purchased new.
Today, if someone signs up to an unlimited plan at one of these services that lets you keep everything you can find for $10/mth each at the age of 16 and keeps that plan until they are 76, you'll spend $7,200 during your entire lifetime.
Sign up at two (2) of these services (for a wider variety of songs that one or the other may not have) and you'll still only spend $14,400 over 50 years. Quite a bargain if you ask me.
And for that first $10 outlay, you've got access to more songs than anyone that's put out $50,000 to purchase all their music.
