We've discussed this before, I'm sure, but what music services do you use? I was finding myself getting into a bit of a rut with Pandora - it seems to have stopped rotating in new songs unless and until I make a conscious addition to the playlist, and then it really gloms onto that artist. I'd never been much into Spotify - it just seemed silly to rotate through multiple services - but given the Pandora problem, I decided to give it more of a try. The weekly curated lists have been excellent - a handful of songs I know, but many more I don't, including some news stuff, deep cuts and covers, many of which I have genuinely enjoyed.
I'm trying not to like or dislike too many songs on the service though, for fear it will become another Pandora, and only cater to my identified likes, when, in fact, the thing I like most is variety and finding new songs.
What services do you use? How do you use them? Drop your lists. Nominate your summer songs. Especially that. Nominate your summer songs!
