I love disclaimers. In the case of the big 58-song summer playlist I've created, there are a few of them. These songs fall into at least one of these categories, sometimes more, sometimes all: they were released during the summer, they were popular during the summer, the song title and/or lyrics refer to summer, sun, heat, etc. If they don't fit these categories -- and this is a pretty big disclaimer -- to me they either sound like a summer-type song or I identify them with summer in my mind for some reason, which will be explained.
Also, the list only includes songs that are in my iTunes library. There may be other songs that are truly summer songs, but if I don't own them I didn't include them. (It's also possible that some songs not on the list but should be are in my iTunes but I somehow neglected to find it.) I am open to any and all suggestions to add to the list, but if it's not obvious from the song title why it should be included I hope you'll enlighten me as to why it's a summer song.
I'm listing them in order of the year of release (according to Wikipedia or whatever other sources I could find). Using the versions I have (a couple of extended mixes included) it's over 4 hours, 15 minutes of music, and Part One begins after the jump:
