So, you?ve finally cottoned on to the fact that having a plethora of playlists downloaded on your iPod is one thing but not having anything worth playing is another. Yep, according to Miles Keylock, it?s time to kick-start a good old-fashioned CD collection. Start by tuning in to the 30 albums you must hear before the big DJ in the sky hits eject...

1. Frank Sinatra: In The Wee Small Hours
A washed-up jazz crooner reinvents himself as a bar stool balladeer. Sinatra?s cool confessions nail his bust-up with babe Ava Gardner. Take a long sip from the bottom of the bottle ennui that makes this the greatest break-up album ever.

2. Hank Williams: 40 Greatest Hits
The only country and western album you?ll ever need to own. Honky tonk?s own Elvis cruises down the original boulevard of broken dreams, narrating his tear-in-my-beer tales of cheating hearts and being 'Whiskey Bent And Hell Bound'.

3. Billie Holiday: Lady In Satin
The blues breaks. Lady Day channels her junkie pride into a set of naked torch songs that provides the fucked-over and fucked-up emotional outline for Janis Joplin, Marianne Faithfull, Courtney Love and countless soul-baring psycho-chicks to come.

4. Miles Davis: Kind Of Blue
This is the most critically-hyped jazz album ever. But it?s worth it just to hear Miles?s impressionistic trumpet tones leading master sax blaster Coltrane into spacious tone poems that actually swing through the silences.

5. Muddy Waters: Muddy Waters At Newport
The album that got Eric Clapton, Jimmy Page and Keith Richards hooked on electric blues. The primal chord-call fuelling 'Hoochie Coochie Man', 'Got My Mojo Working' and 'Baby Please Don?t Go' inject sex straight into the whole rock ?n roll equation.

6. Bob Dylan: Highway 61 Revisited
Folk music plugs in. This was Dylan?s electric move and quickly elevated his freewheelin? verse from hippie-protest poems to a singer-songwriter who actually sounds like he makes a difference, man.
