If you're spending a minute to find the groove on a 7" then you're doing it wrong, but consider putting some tape on your records to bump your needle to the start of the track.
Well, obviously you have to count in a 10 beer handicap and darkly lit room... yeah, it was a hyperbole
But it really is true that sometimes it's a bitch to find the right groove on colored, especially transparent, vinyl. I DJ weekly and I only play 7"'s and sometimes you don't just have that extra second it takes when you are playing a 30 second track and five drunkards are yelling at your ear so you can't use your headphones either.
And RE: sound quality, it doesn't matter as much these days as pressing techniques have changes (mostly visible on how shallow the grooves are nowadays: you can barely squeeze 6 minutes of stuff on 33rpm 7" (yeah, another thing I dislike! 33rpm 7"'s!) while I have some records, like Flamin' Groovies Slow Death 7"EP that not only is a 45, is also like 8 minutes long from each side! Which is why it often serves my toilet break record, Slow Death and Tallahassee Lassie combo is unbeatable!
Which also brings us back to my absolute favorite format, the god of music formats, the unbeatable one: 7" single. It's hard to do a competent full length but the real hard part is doing a single that has like 2 minutes of music per side with people going "whoa that's great!" instead of "I wish there were more tracks..". As pressing of vinyl is kinda expensive these days, many bands/labels easily cram the records full, which doesn't actually improve the quality of the package. Less is more. But obviously if you have 4 killer songs, I have nothing against a killer 4 track EP.
So yeah, I don't have anything much against colored vinyl, it just doesn't offer anything extra for me. But if people start to say how much they love picture discs, I am going to a total internet nerd rage mode.
