Vinyl is definitely making a come-back. My hubby and I like to go see emerging bands at bars and small clubs, and over the past few years more and more of them have vinyl EPs and LPs at their "merch" tables. The reasons people have told us range from liking the "warm" sound of vinyl, to the ability to better control pirating, but also just the coolness/hipster factor. Of course most of us ditched our turntables within the past 10 years, just in time for vinyl to come back in vogue.
And yes, we are starting to see cassettes show up on the merch tables too. I haven't seen any 8-tracks though!
