What vinyl albums did you buy recently?
I found some Leon Russell and Elton John records at a yard sale last weekend. 
Leon Russell's work touched millions of rock and roll fans. He was a great musician and songwriter! How many albums are in your collection?
I only have two Leon Russell records, I don't know a lot about him honestly. He was my Dad's favorite singer though. In my entire collection, I've got about 30 records. I try to only buy things that I really like or that mean something, not just buy to build up my collection. 
The cheapest vinyls can be found on amazon and ebay, but i hear right now but barnes and nobles has some deals too if youre in the market for more!
I like to look at what B& N has when I go in there for books. It's kind of crazy to me how records sort of died out and now it's a prestige thing to get your music on vinyl. It's also nuts to me that things like the Guardians of the Galaxy soundtrack are on records. 
It is definitely a current fad! Experts in the music industry do not expect the boom to continue once the fad is over. Streaming is the default way to listen to music these days.
I love streaming and playlists an everything but vinyl is a special format, it gives music depth. Like, you can feel the grooves on the record in the sound when you play it. That's why I try to limit my buys to just stuff that I feel deserves to be heard in the format. 
Do you own a record washer? A clean record will give superior sound over a dirty one.
No, I've never even heard of one. How do you wash a record without scratching it though? 
There are record cleaning machines. cleanervinyl.com sells them among other retailers. Other retailers are likely cheaper than cleanervinyl.com
